Som det vil være klart for en fagmann i organisk kjemi, har alle forbindelsene to strukturelle asymmetriske sentre og kan foreligge både i cis og trans konfigurasjonen. As will be apparent to one skilled in organic chemistry, all of the compounds have two structural asymmetric centers and can exist in both the cis and trans configurations.
I de fleste tilfeller erholdes en blanding av de to steriske isomere ved fremgangsmåten som skal beskrives i detfølgende og en tilsvarende separasjon kan eventuelt være nødvendig. In most cases, a mixture of the two steric isomers is obtained by the method to be described below, and a corresponding separation may possibly be necessary.
I andre tilfeller er dog dannelsen av en enkelt isomer så fremherskende at det nærmer seg 100$, og en separasjon er da ikke påkrevet hvis ikke produktet ønskes i en analytisk ren form til studieformål. In other cases, however, the formation of a single isomer is so predominant that it approaches 100$, and a separation is then not required if the product is not desired in an analytically pure form for study purposes.
Konfigurasjonen til cis og trans isomerene med strukturen ble tildelt over H NMR (Kjerne Magnetisk Resonans) spektre ved bestemmelse av de karakteristiske koblingskonstanter (Jc_1>c_2) for flere forbindelser. Nevnte spektre viser C-l-H som en dublett med J=9,7 - 10,23 Hz i transderivatene og J= 2,5 -3,5 Hz i cisderivatene. The configuration of the cis and trans isomers of the structure was assigned over H NMR (Nuclear Magnetic Resonance) spectra by determining the characteristic coupling constants (Jc_1>c_2) for several compounds. Said spectra show C-1-H as a doublet with J=9.7 - 10.23 Hz in the trans derivatives and J= 2.5 -3.5 Hz in the cis derivatives.
I serien med forbindelser med strukturenIn the series of connections with the structure
ble konfigurasjonen tildelt under anvendelse av NOE (Nuclear Overhauser Effeet). (J.H. Noggle and R.E. Schirmer, the Nuclear Overhauser Effeet, Academic Press, London, 1971). Den enkle besstemmelse av koblingskonstanter over ^H NMR er ikke indikativ, da forskjellene mellom dem er meget små. the configuration was assigned using NOE (Nuclear Overhauser Effect). (J.H. Noggle and R.E. Schirmer, the Nuclear Overhauser Effect, Academic Press, London, 1971). The simple determination of coupling constants via ^H NMR is not indicative, as the differences between them are very small.
I tillegg til NOE ble cis- trans konfigurasjonen også bekreftet ved hjelp av IR-spektroskopi (H.J.Rimeke et al. Liebigs Ann.Chem. 726, 25-29, 1969). Spektrene til de enkelte isomere ble tatt opp i forskjellige konsentrasjoner under anvendelse av metylendiklorid. Det er velkjent at kun cis-serien danner Intra-molekylære hydrogenbindiger. I foreliggende tilfelle forblir derfor intensitetsforholdet mellom det frie hydroksylbåndet og det til bundet hydroksyl konstant ved progressiv fortynning, mens i transserien forandres dette forhold betraktelig til fordel for det frie hydroksylbånd. In addition to NOE, the cis-trans configuration was also confirmed by means of IR spectroscopy (H.J.Rimeke et al. Liebigs Ann.Chem. 726, 25-29, 1969). The spectra of the individual isomers were recorded in different concentrations using methylene dichloride. It is well known that only the cis series forms intra-molecular hydrogen bonds. In the present case, therefore, the intensity ratio between the free hydroxyl band and that of the bound hydroxyl remains constant upon progressive dilution, while in the trans series this ratio changes considerably in favor of the free hydroxyl band.
Den kjemiske fremgangsmåte for fremstilling av forbindelsene i henhold til oppfinnelsen består i å omsette et brom-keton med delformel IV med et sekundært amin for å danne aminoketonet med delformel V. The chemical method for producing the compounds according to the invention consists in reacting a bromo-ketone of partial formula IV with a secondary amine to form the amino ketone of partial formula V.
Aminoketonet hydrogeneres deretter for å danne den ønskede aminoalkohol The amino ketone is then hydrogenated to form the desired amino alcohol
Avhengig av betingelsene kan aminoketonet V isoleres fra reaksjonsblandingen før den hydrogeneres. På den annen side Depending on the conditions, the amino ketone V can be isolated from the reaction mixture before it is hydrogenated. On the other hand
hvis mellomproduktet V utviser en lav stabilitetsgrad, er det foretrukket å hydrogenere det direkte i reaksjonsblandingen, i hvilken det dannes ved omsetning av bromketonet med det sekundære aminet. if the intermediate V exhibits a low degree of stability, it is preferred to hydrogenate it directly in the reaction mixture, in which it is formed by reaction of the bromoketone with the secondary amine.
Det første trinn i fremgangsmåten utføres i nærvær av en protonakseptor, såsom et alkalimetall eller jordalkali metallkarbonat eller bikarbonat, eller et tertiært amin. The first step of the process is carried out in the presence of a proton acceptor, such as an alkali metal or alkaline earth metal carbonate or bicarbonate, or a tertiary amine.
I noen tilfeller kan et overskudd over den molekylære mengde av det samme sekundære amin som ansettes med bromketonet anvendes med tilfredsstillende resultater. Vanligvis utføres dette første trinn i et inert løsningsmiddel, såsom en lavere alkanol, f.eks. metanol eller etanol, eller et keton såsom et di-lavere alkylketon, f.eks. aceton eller metyl-keton. Det er uviktig om aminet tilsettes til bromketonet, mens begge eller kun en av dem er oppløst i løsningsmidlet, eller omvendt at bromketonet tilsettes til aminet, og at fremdeles begge er i oppløsning eller kun en av dem. Den hensiktsmessige måte å gjennomføre det første trinn, vil velges avhengig av egenskapene til reaktantene og deres reaktivitet. Reaksjonstemperaturen tilpasses også avhengig av reaktiviteten til de to reaktanter, selv om det vanligvis foretrekkes koketemperaturen til løsningsmidlet. In some cases an excess over the molecular amount of the same secondary amine employed with the bromoketone can be used with satisfactory results. Usually this first step is carried out in an inert solvent, such as a lower alkanol, e.g. methanol or ethanol, or a ketone such as a di-lower alkyl ketone, e.g. acetone or methyl ketone. It is unimportant whether the amine is added to the bromoketone, while both or only one of them is dissolved in the solvent, or conversely that the bromoketone is added to the amine, and both are still in solution or only one of them is. The appropriate way to carry out the first step will be chosen depending on the properties of the reactants and their reactivity. The reaction temperature is also adjusted depending on the reactivity of the two reactants, although the boiling temperature of the solvent is usually preferred.
Det andre trinn i fremgangsmåten, dvs. hydrogenereingen, kan utføres ved enhver konvensjonell hydrogeneringsfrem-gangsmåte som vil omdanne et keton til en hydroksygruppe. The second step in the process, i.e. the hydrogenation, can be carried out by any conventional hydrogenation process which will convert a ketone into a hydroxy group.
Vi har dog funnet at hydrogeneringen best utføres ved å anvende et metallhydrid, fortrinnsvis et dobbelthydrid, såsom NaBH4, LiAlH4, osv. ved konvensjonelle fremgangsmåter i et løsningsmiddel som er inert til hydrogenerisngsreak-sjonen, som i tilfelle NaBH4kan være vann eller en lavere alkanol, såsom metanol eller etanol, begge i nærvær av va-rierende mengder av vann eller vannfrie betingelser; eller alternativt når det f.eks. anvendes L1A1H4kan løsningsmid-let være en dietyleter, tetrahydrofuran eller lignende, ved en temperatur som kan ligge i området fra 5 °C til koketemperaturen for det valgte løsningsmiddel. However, we have found that the hydrogenation is best carried out by using a metal hydride, preferably a double hydride, such as NaBH4, LiAlH4, etc. by conventional methods in a solvent that is inert to the hydrogenation reaction, which in the case of NaBH4 can be water or a lower alkanol, such as methanol or ethanol, both in the presence of varying amounts of water or anhydrous conditions; or alternatively when it e.g. if L1A1H4 is used, the solvent can be a diethyl ether, tetrahydrofuran or the like, at a temperature that can lie in the range from 5 °C to the boiling temperature of the chosen solvent.
Når mellomproduktet ikke isoleres fra reaksjonsblandingen til det første reaksjonstrinn, og avhengig av naturen til det valgte hydrogeneringsmiddel, kan dette tilsettes direkte til mellomproduktreaksjonsblandingen, enten i form av en oppløsning i et hensiktsmessig løsningsmiddel, som ikke griper inn i hydrogeneringen og oppløsningen av hydrogeneringsmidlet tilsettes under opprettholdelse av blandingen på tilbakeløpstemperaturen eller ved en lavere temperatur som kan finnes å være mer hensiktsmessig, avhengig av den observerte reaksjonshastighet; eller hydrogeneringsmidlet kan tilsettes posjonsvis eller dråpevis tilsetting av dets oppløsning i et egnet oppløsningsmiddel, under opprettholdelse av reaksjonsblandingen på 0-5 C inntil tilsetning er fullført, og deretter å oppvarme blandingen til koking under tilbakeløp inntil omsetningen er fullstendig. When the intermediate product is not isolated from the reaction mixture of the first reaction step, and depending on the nature of the selected hydrogenating agent, this can be added directly to the intermediate reaction mixture, either in the form of a solution in a suitable solvent, which does not interfere with the hydrogenation and the solution of the hydrogenating agent is added under maintaining the mixture at the reflux temperature or at a lower temperature that may be found to be more appropriate, depending on the observed reaction rate; or the hydrogenating agent may be added by portionwise or dropwise addition of its solution in a suitable solvent, maintaining the reaction mixture at 0-5 C until addition is complete, and then heating the mixture to reflux until the reaction is complete.
Selvsagt vil en fagmann velge en fremgangsmåte som er hensiktsmessig når det gjelder naturen til hydrogeneringsmidlet og substratet, og reaktanten som anvendes. Of course, a person skilled in the art will choose a method which is appropriate in terms of the nature of the hydrogenating agent and the substrate, and the reactant used.
En alternativ fremgangsmåte ved fremstilling av forbindelsen i henhold til oppfinnelsen, består av å sette en aminoalkohol med delformel VI metaldehyd med delformel VII ved en temperatur på mellom 0°C og 20 °C i et løsningsmddel, fortrinnsvis en lavere alkanol An alternative method for the preparation of the compound according to the invention consists of placing an amino alcohol with partial formula VI metaldehyde with partial formula VII at a temperature of between 0°C and 20°C in a solvent, preferably a lower alkanol
såsom metanol eller etanol under tilsetning i posjoner av et hydrogeneringsmiddel, fortrinnsvis valgt fra metallhydrider eller doble hydrider eller doble cyanohydrider, såsom natriumborcyanohydrid eller litiumborcyanohydrid, hvorav disse siste hydrogenerisngsmidler er foretrukket. such as methanol or ethanol during the addition in portions of a hydrogenating agent, preferably selected from metal hydrides or double hydrides or double cyanohydrides, such as sodium boron cyanohydride or lithium boron cyanohydride, of which these last hydrogenating agents are preferred.
Når tilsetningen av hydrogeneringsmidlet avsluttes, får blandingen langsomt nå romtemperatur for å fullføre reaksjo-nen. When the addition of the hydrogenating agent is finished, the mixture is slowly allowed to reach room temperature to complete the reaction.
Det vil være klart for en fagmann i organisk kjemi at den sist beskrevne fremstillingsmåte er hensiktsmessig når symbolet X i delformel VII ovenfor representerer en lineær eller forgrenet alkylgruppe. It will be clear to a person skilled in organic chemistry that the last described method of preparation is appropriate when the symbol X in partial formula VII above represents a linear or branched alkyl group.
Alternativt kan hydrogeneringen urføres under anvendelse av konvensjonelle fremgangsmåter, såsom hydrogen i nærvær av en katalysator. Alternatively, the hydrogenation can be carried out using conventional methods, such as hydrogen in the presence of a catalyst.
Forbindelsene i henhold til denne oppfinnelse utviser antihypertensiv, blodplateaggregasjonshemmende, hypolipe-misk, antianoksisk, spasmolytisk, antitrombotisk og CA<++>antagoniserende aktivitet. The compounds of this invention exhibit antihypertensive, antiplatelet aggregation, hypolipemic, antianoxic, spasmolytic, antithrombotic and CA<++>antagonizing activity.
Den antihypertensive aktivitet ble testet på en gruppe avThe antihypertensive activity was tested on a group of
5 SH-rotter (spontant hypertensive rotter) på 5 DOCA rotter (deoksycortikosteron acetat og netriumklorid ladede rotter), som veide 200 + 10 g, og var fastende i 18 timer og behandlet oralt med forbindelsene i henhold til oppfinnelsen suspendert i 0,5$ gummi arabicum. 5 SH rats (spontaneously hypertensive rats) of 5 DOCA rats (deoxycorticosterone acetate and sodium chloride loaded rats), which weighed 200 + 10 g, and were fasted for 18 hours and treated orally with the compounds according to the invention suspended in 0.5$ gum arabic.
Forandringer i blodtrykk (mm Hg) før (T=0) og etter behandling (2,4 og 6 timer) ble målt I henhold til fremgangsmåten med halearterie pletysmografi som beskrevet i ["Spontane-ously hypertensive rats (SKR), guidelines for breeding, care and use", SKR Conference, 1976, side 11.] Changes in blood pressure (mm Hg) before (T=0) and after treatment (2, 4 and 6 hours) were measured according to the method of tail artery plethysmography as described in ["Spontaneously hypertensive rats (SKR), guidelines for breeding , care and use", SKR Conference, 1976, page 11.]
Hjertehastigheten ble også undersøkt (BP Recorder No. 8006 levert av Basile, Comerio, Italia). Det arterielle trykk før behandling var 210 + 10 mmHg i SKR og 200 + 10 i DOCA rotter. Heart rate was also examined (BP Recorder No. 8006 provided by Basile, Comerio, Italy). The arterial pressure before treatment was 210 + 10 mmHg in SKR and 200 + 10 in DOCA rats.
Tabell I viser at de testede forbindelser er i besittelse av stor antihypertensivitet. Table I shows that the tested compounds possess great antihypertensive activity.
Den maksimale effekt ble nedtegnet 2-4 timer etter behandlig og varigheten av effekten var mere enn 6 timer; i dette tidsrom ble det ikke registrert bemerkelsesverdig økning av hj"ertehastigheten. Noen av forbindelsene ble testet på SH-rotter, en dose på 1 og/eller 5 mg/kg og deres aktivitet syntes å være doseavhengig. F.eks. forårsaket administrering av 5 mg/kg p.o. av MG 28401, M 28427 og MG 38007 en trykksenkning på henholdsvis 37,6, 26,2 og 20 mm Hg. Administrering av 1 mg/kg p.o. av NG 28427 forårsaker en trykksenkning på 17,4 mm hg. The maximum effect was recorded 2-4 hours after treatment and the duration of the effect was more than 6 hours; during this period no remarkable increase in heart rate was recorded. Some of the compounds were tested in SH rats, a dose of 1 and/or 5 mg/kg and their activity appeared to be dose-dependent. For example, the administration of 5 mg/kg p.o. of MG 28401, M 28427, and MG 38007 a BP reduction of 37.6, 26.2, and 20 mm Hg, respectively. Administration of 1 mg/kg p.o. of NG 28427 causes a BP reduction of 17.4 mm Hg.
Under de samme betingelser var tobalosin lite aktiv i en dose på 5 mg/kg p.o. (trykksenkning 13 mm Hg). For å teste antagonismen mot fenylefrin (PHE) indusert hypertensjon ble hanrotter Cri:CD (SD)BR bedøvet med uretan, 1 g/kg i.p. Under the same conditions, tobalosin was little active at a dose of 5 mg/kg p.o. (pressure drop 13 mm Hg). To test the antagonism against phenylephrine (PHE) induced hypertension, male Cri:CD (SD)BR rats were anesthetized with urethane, 1 g/kg i.p.
PHE ble administrert simultativt og dose-responskurver ble erholdt (kontroller). Doseresponskurvene ble likeledes erholdt etter administrering av forsøksmedikamenter (1 mg/kg i.v.). Fra de to kurver ble den PHE dose beregnet som forårsaket en 50 mm Hg økning av det arterielle trykk. PHE dosen var ca. 3 ganger, sammenlignet med kontrollene, etter administrering av MG 28401 og MG 28427, og ca. 9 ganger etter administrering av MG 38007, MG 38060, MG 38041. PHE was administered simultaneously and dose-response curves were obtained (controls). The dose-response curves were also obtained after administration of experimental drugs (1 mg/kg i.v.). From the two curves, the PHE dose that caused a 50 mm Hg increase in arterial pressure was calculated. The PHE dose was approx. 3 times, compared to the controls, after administration of MG 28401 and MG 28427, and approx. 9 times after administration of MG 38007, MG 38060, MG 38041.
Beskyttelsemot toksiske adrenalindoser ble testet som følger. Grupper på 10 - 20 hanmus CrI:CD 1(CR) BR ble behandlet oralt med bærer (kontroller) og med forskjellige doser av forbindelsene. Etter 2 timer ble 14,5 mg/kg av 1-adrenalin administrert intraperitorialt og mortalitet ble nedtegnet etter 24 timer; i kontrollene var mortaliteten 100$. Fra log-dose-$ beskyttelseskurver ble de 50$ beskyt-tende doser beregnet (Litchfield et al., J.Pharmakol. Exp. Ther. 96, 99, 1949). Protection against toxic epinephrine doses was tested as follows. Groups of 10 - 20 male CrI:CD 1(CR) BR mice were treated orally with vehicle (control) and with various doses of the compounds. After 2 hours, 14.5 mg/kg of 1-adrenaline was administered intraperitorially and mortality was recorded after 24 hours; in the controls the mortality was 100$. From log-dose-protection curves, the 50$ protective doses were calculated (Litchfield et al., J.Pharmakol. Exp. Ther. 96, 99, 1949).

Reseptorbindingsforsøket for binding av<3>H-pazosin,<3>H-klonidin og<3>H-spiperon-bindingen til rottehjernemembranen ble utført i henhold til [Greenberg et al., Life Sei. 19, 69, 1976, and U'Prichard et al., Molec. Pharmacol. 13, 454, 1977.] Table 2 shows the results obtained with some of the compounds compared to known drugs. The receptor binding assay for the binding of <3>H-pazosin, <3>H-clonidine and <3>H-spiperone binding to the rat brain membrane was performed according to [Greenberg et al., Life Sei. 19, 69, 1976, and U'Prichard et al., Molec. Pharmacol. 13, 454, 1977.]
Data for de testede forbindelser er oppført i tabell 3, hvor 50$ hemmende konsentrasjoner (IC50) av tibalosine og urapidil også er oppført. Forbindelsene i henhold til oppfinnelsen utviser en god affinitet mot cx^-adrenergiske reseptorer, sammenlignbar med eller høyere enn de to smmenligningssubstanser, og dårlig eller ingen affinitet mot oc2-adrener6iske reseptorer. Data for the compounds tested are listed in Table 3, where the 50% inhibitory concentrations (IC50) of tibalosine and urapidil are also listed. The compounds according to the invention show a good affinity towards cx-adrenergic receptors, comparable to or higher than the two comparison substances, and poor or no affinity towards oc2-adrenergic receptors.
En moderat affinitet mot serotoninergiske2(5-HT2) reseptorer utvises av MG 38007 og MG 28401. Effekten på blodplateaggregasjonen ble testet ex vivo i henhold til fremgangsmåten til Minsker. (J. Pharmacol. Exp. Ther. 210, 37, 1979) noe modifisert. Grupper på 3 rotter (280-350 g) ble behandlet oralt med bærer (kontroller) og forbindelser (0,15 mM/kg). Blod ble tatt og samlet fra rotter i hver grupper 1 time etter behandling og det blodplaterike plasma (PRP) ble separert ved sentrifugering. A moderate affinity towards serotoninergic 2(5-HT2) receptors is shown by MG 38007 and MG 28401. The effect on platelet aggregation was tested ex vivo according to the method of Minsker. (J. Pharmacol. Exp. Ther. 210, 37, 1979) somewhat modified. Groups of 3 rats (280-350 g) were treated orally with vehicle (control) and compounds (0.15 mM/kg). Blood was drawn and collected from rats in each group 1 hour after treatment and the platelet-rich plasma (PRP) was separated by centrifugation.
Blodplateaggregasjonen ble stimulert med kollagen (2-4-mcg/ml) tilsatt simultant til PRP for kontroller og behand-lede rotter. Resultatene ble vurdert fotometrisk. Hvert forsøk ble gjentatt 4 ganger i grupper på 3 dyr. Aggrega-sjonskurvene ble evaluert med hensyn til to parametre, nemlig maksimal optisk densitetsvariasjon ( maksimalaggrega-sjon) og aggregasjonshastighet. Platelet aggregation was stimulated with collagen (2-4-mcg/ml) added simultaneously to PRP for control and treated rats. The results were evaluated photometrically. Each experiment was repeated 4 times in groups of 3 animals. The aggregation curves were evaluated with regard to two parameters, namely maximum optical density variation (maximum aggregation) and aggregation rate.
Tabell 4 viser effekten nedtegnet etter behandling med noen av de testede forbindelser. De viser en aktivitet som er sammenlignbar med ticlopidin og suloctidil og kun noe lavere enn dipiridamol. Sprague Dawley Nos hanrotter (180-200 g) ble behandlet oralt i 4 etterfølgejnde dager med bærer (0,5 ml/100 gummi arabicum 2,5 $, kontroll) og med 1-2 doser av forsøksforbin-delsene, og ble ofret den femte dagen etter 18 timers fasting. Total kolesterol (CHOL), triglycerider (TG), HDL kolesterol (CHOL-HDL) ble bestemt i serum og leveren ble veid. Table 4 shows the effect recorded after treatment with some of the tested compounds. They show an activity comparable to ticlopidine and suloctidil and only somewhat lower than dipyridamole. Male Sprague Dawley Nos rats (180-200 g) were treated orally for 4 consecutive days with vehicle (0.5 ml/100 gum arabic $2.5, control) and with 1-2 doses of the test compounds, and were sacrificed on fifth day after 18 hours of fasting. Total cholesterol (CHOL), triglycerides (TG), HDL cholesterol (CHOL-HDL) were determined in serum and the liver was weighed.
Tabell 5 gir de erholdte resultater. MG 38112 forårsaker en betraktelig senkning av både CHOL og TG mens MG 38041, MG 38128 og MG 38131 senker TG og øker CHOL-HDL. Table 5 gives the results obtained. MG 38112 causes a considerable lowering of both CHOL and TG while MG 38041, MG 38128 and MG 38131 lower TG and increase CHOL-HDL.
Levervekten ble ikke berørt. Effekten av MG 38112 og MG 38131 er høyere enn med Clofibrate, hvilken som kjent forårsaker en betraktelig leverøkning. Probucol-aktiviteten er moderat og bemerkes kun etter langvarig behandling (8 dager). Liver weight was not affected. The effect of MG 38112 and MG 38131 is higher than with Clofibrate, which is known to cause considerable liver enlargement. Probucol activity is moderate and is noted only after prolonged treatment (8 days).
Den antihypoksiske aktivitet ble bestemt i henhold til The antihypoxic activity was determined according to
[Yasuda et al., Arch. Int. Pharmacodyn. 233,136, 1978.][Yasuda et al., Arch. Int. Pharmacodyn. 233,136, 1978.]
Grupper på 10 hanmus (21-23 g) ble behandlet oralt med bærer (kontroller) og forbindelsen i henhold til oppfinnelsen. Etter 45 eller 90 minutter ble dyrene halshugd og krampetre-kningtiden ble bestemt. Tabell 6 viser resultatene erholdt etter administrering av noen av forbindelsene i henhold til oppfinnelsen, hvilke utviser en høyere aktivitet enn Suloctidil. Den orale akutte toksisitet i hanmus for forbindelser i henhold til oppfinnelsen er meget lav. F.eks. er LD5g høyere enn 500 mg/kg for MG 38041, MG 28400 og MG 38100, høyere enn 1.000 mg/kg for MG 38019, Mg 38006, MG 38112 og MG 38107; og høyere enn 2.000 mg/kg for MG 38005, MG 28401, MG 28414 og MG 28427. Groups of 10 male mice (21-23 g) were treated orally with vehicle (control) and the compound according to the invention. After 45 or 90 minutes, the animals were decapitated and the seizure duration was determined. Table 6 shows the results obtained after administration of some of the compounds according to the invention, which show a higher activity than Suloctidil. The oral acute toxicity in male mice for compounds according to the invention is very low. E.g. is LD5g higher than 500 mg/kg for MG 38041, MG 28400 and MG 38100, higher than 1,000 mg/kg for MG 38019, Mg 38006, MG 38112 and MG 38107; and higher than 2,000 mg/kg for MG 38005, MG 28401, MG 28414 and MG 28427.

Ved hydrogenering med NaBH4ble den eneste cis formen isolert i 47,8$ utbytte. Ved å bruke LiAlR"4 som hydrogeneringsmiddel erholdes en blanding av els og trans-formene og separeres ved kromatografi over silicagel. Utbytte var 27,9$ i cis og 37,8$ i trans form. On hydrogenation with NaBH4, the only cis form was isolated in 47.8$ yield. By using LiAlR"4 as a hydrogenating agent, a mixture of els and the trans forms is obtained and separated by chromatography over silica gel. The yield was 27.9$ in the cis and 37.8$ in the trans form.
