Abstract

New 14, 15-dihydroeburnamenine derivs. are of formula (I) (where R is H, 10- or 11- halogen, 11-amino, 11-formamido or 2-5C 11-alkylamino) (Ie and their acid addn. salts are psychostimulants and increase vigilance. (I) can be used to treat cerebral vascular disorders, cerebral sclerosis, cerebral insufficiency and loss of memory resulting from knocks on the head. (I) are prepd. by hydration in the 14, 15-posn. of the corresp. (3S,16S)eburnamenine in the presence of a noble metal catalyst, e.g. platinum oxide.

Description

Neue organische Verbindungeh, ihre HerstellungNew organic compounds, their production

und Verwendung Gegenstand der Erfindung sind Verbindunggen der Formel I, worin R Wasserstoff in 10- oder 11-Stellung ständiges Fluor, Chlor, Brom oder Jod, eine in ll-Stellung ständige Gruppe der Reihe Amino oder Formamido oder eine ll-Alkanoylaminogruppe mit 2 bis 5 Kohlenstoffatomen bedeutet, in Form der Basen oder von Säureadditionssalzen, R steht insbesondere für Wasserstoff, 10-Fluor, 10-Brom und ll-Brom.and Use The invention relates to compounds of the formula I, wherein R is hydrogen in the 10- or 11-position fluorine, chlorine, bromine or Iodine, a group in the II-position of the series amino or formamido or a II-alkanoylamino group with 2 to 5 carbon atoms means in the form of bases or of acid addition salts, R is in particular hydrogen, 10-fluorine, 10-bromine and ll-bromine.

Erfindungsgemäss gelangt man zu den Verbindungen der Formel I. indem man Verbindungen der Formel II, worin R obige Bedeutung besitzt, in 14,15-Stellung hydriert.According to the invention, the compounds of the formula I are obtained by one compounds of the formula II, where R has the above meaning, hydrogenated in the 14,15 position.

Das erfindungsgemässe Verfahren kann analog zu bekannten Methoden durchgeführt werden.The method according to the invention can be carried out analogously to known methods be performed.

Man hydriert zweckmässig in Gegenwart eines Edelmetallkatalysators wie Palladium, Raney-Nickel oder Platin.It is expedient to hydrogenate in the presence of a noble metal catalyst such as palladium, Raney nickel or platinum.

Die jlydrierung kann bei Raumtemperatur durchgeführt werden.The hydration can be carried out at room temperature.

Die nach dem erfindungsgemässen Verfahren erhältlichen Verbindungen der Formel I können in freier Form als Base, oder in Form ihrer Additionssalze mit Säuren vorliegen.The compounds obtainable by the process according to the invention of the formula I can be used in free form as a base, or in the form of their addition salts with Acids are present.

Aus den frcien Basen lassen sich in bekannter Weise Säureadditionssalze herstellen und umgekehrt.Acid addition salts can be prepared from the French bases in a known manner manufacture and vice versa.

Zur Salzbildung können z.B. folcjende Säuren verwendet werden: Chlorwassrstoff-, Schwefel-, Phosphor-, Wein-, Malein- und Methansulfonäure.Folic acids, for example, can be used to form salts: Hydrogen chloride, Sulfuric, phosphoric, tartaric, maleic and methanesulfonic acids.

Die Ausgangsprodukte sind bekannt oder analog zu bekannten Methoden, beispielsweise wie im experimentellen Teil beschrieben, herstellbar.The starting products are known or analogous to known methods, for example, as described in the experimental part, can be produced.

Die Verbindungen der Formel I in freier Form oder in From von Additienssaizen mit physiologisch verträglichen Säuren (erfindungsgemässe Verbindungen) zeichnen sich durch interessante pharmakologische Eigenschaften aus und können daher als Heilmittel Verwendung finden.The compounds of the formula I in free form or in the form of additives draw with physiologically compatible acids (compounds according to the invention) are characterized by interesting pharmacological properties and can therefore be used as Find remedies use.

So sind sie nützlich, da sie vigilanzwrhöhende und psychostimulierende Eigenschaften besitzen.So they are useful as they are vigilance-increasing and psychostimulating Possess properties.

Die crifindungsgemässen Verbindungen sind deshalb indiziert bei zerebralen Gefässchädigungen, bei der Zerebralskelerose, bei Zerebralinsuffizienz oder ei Bewusstseinsverlusten aufgrund von Schädeltraumata.The connections according to the invention are therefore indicated for cerebral ones Vascular damage, in cerebral kerosis, in cerebral insufficiency or a loss of consciousness due to head trauma.

Die Erfindung betrifft auch Heilmittel, die eine Verbindung der Formel I in freier Form oder in Form ihrer physiologisch verträglichen Additionssalze mit Säuren enthalten. Diese ileilmittel, beispielsweise eine Lösung oder eine Tablette, können nach bekannten Methoden, unter Verwendung der üblichen Hilfs- und Trägerstoffe, hergestellt werden.The invention also relates to medicaments containing a compound of the formula I in free form or in the form of their physiologically acceptable addition salts with Contain acids. These drugs, such as a solution or tablet, can by known methods, using the usual auxiliaries and carriers, getting produced.

Alle Temperaturagaben erfolgen in Celsiusgraden. All temperatures are given in degrees Celsius.

Beispiel: (3s, 16s)-14,15-Dihydroeburnamenin 200 mg Platinoxid wurden in 5 ml Essigsäure vorhydriert, dazu eine Lösung von 2,78 g (10 mol) (3s,16s)-Eburnamenin in 5 ml Essigsäure gegeben und das Gemisch 2 Tage bei 740 Torr und Zimmertemperatur hydriert.Example: (3s, 16s) -14,15-Dihydroeburnamenin 200 mg of platinum oxide were Pre-hydrogenated in 5 ml of acetic acid, plus a solution of 2.78 g (10 mol) (3s, 16s) -Eburnamenin in 5 ml of acetic acid and the mixture for 2 days at 740 torr and room temperature hydrogenated.

Nach Filtration durch Celite, Abdampfen des Lösungsmittels im Vakuum, Verteilen des Rückstandes zwischen 20 ml 2N Ammoniak und 20 ml Methylenchlorid und Eindampfen der organischen Phase verblieb öliges (3s, 16s)-14,15-Dihydroeburnamenin, welches nach der Bildung von Kristallkeimen aus 2-Propanol bei 0° kristallisiert werden konnte.After filtration through Celite, evaporation of the solvent in vacuo, Distribute the residue between 20 ml of 2N ammonia and 20 ml of methylene chloride and Evaporation of the organic phase remained oily (3s, 16s) -14,15-dihydroeburnamenine, which crystallizes after the formation of crystal nuclei from 2-propanol at 0 ° could be.
