Description
Verfahren zur Darstellung von 17-Nethyl-androstanol-17-on-3. Es wurde gefunden, dass man 17-Methyl- androstanol-17-on-3 erhält, ein Produkt von grosser physiologischer Wirksamkeit, das für pharmazeutische Zwecke dient, wenn man ein 17-Methyl-androstanol-(3), welches in 17-Stellung einen Substituenten besitzt, welcher durch Hydrolyse durch die OH- Gruppe ersetzt wird, der Einwirkung eines Oxydationsmittels unterwirft,
welches eine sekundäre Alkoholgruppe in eine Ketogruppe überzuführen vermag und das so erhaltene Produkt hydrolysiert.
Als Oxydationsmittel kommen alle be kannten oxydierend wirkenden Produkte in Betracht, wie sie zum Beispiel in Houben- Weyl "Methoden der organischen Chemie", 3. Auflage, Bd. 2, S. 45 ff (1925) angeführt sind. Kupferoxyd und Chromsäure sind jedoch bevorzugte Mittel. Die Oxydation ist aber auch mit Bichromat und Säure durch führbar. Ferner können Permanganat und andere Persalze, auch Peroxyde wie Wasser stoffsuperoxyd an die Stelle der vorerwähnten Oxydationsmittel treten.
Die Isolierung der gebildeten Ketover- bindungen kann mit Hilfe von Ketonreagen- zien, wie z. B. Semicarbazid, Hydroxylamin, Phenylhydrazin und andere oder mit Hilfe der fraktionierten Kristallisation oder der gleichen erfolgen. Die neue Verbindung lässt sich vorteilhaft aus Essigester umkristalli- sieren und schmilzt bei 192-193 C.
Sie kann als solche therapeutische Verwendung finden, lässt sich aber auch als Zwischen produkt für die Herstellung anderer thera peutisch wertvoller Stoffe benutzen.
<I>Beispiel:</I> 3,5 g 17-Methyl-androstandiol-3-17-mono- aoetat-17 werden in 100 cm' Eisessig gelöst und dazu ein Lösung von 1,3 g Chromsäure anhydrid in 20 cm' 90%iger Essigsäure bei Zimmertemperatur zugegeben. Nachdem man das Reaktionsgemisch 1 Tag stehen gelassen hat, wird es in Wasser gegossen und mit Äther extrahiert. Die ätherische Lösung wird mit Alkalilauge und Wasser gewaschen, vom Wasser befreit und zur Trockne ver- dampft.
Nach Umkristallisieren des Rück standes aus verdünntem Alkohol erhält man das Acetat des 17-llethyl-androstanol-17- on-3. Aus dem Acetat wird durch Versei fung das 17-bletli,#rl-androstanol-17-on-3 her gestellt.
Process for the preparation of 17-Nethyl-androstanol-17-one-3. It has been found that 17-methyl-androstanol-17-one-3, a product of great physiological activity which is used for pharmaceutical purposes, is obtained if a 17-methyl-androstanol- (3) which is in the 17-position has a substituent which is replaced by the OH group by hydrolysis, subject to the action of an oxidizing agent,
which is able to convert a secondary alcohol group into a keto group and hydrolyzes the product thus obtained.
All known oxidizing products can be used as oxidizing agents, such as those listed, for example, in Houben-Weyl "Methods of Organic Chemistry", 3rd Edition, Vol. 2, pp. 45 ff (1925). However, copper oxide and chromic acid are preferred agents. The oxidation can also be carried out with bichromate and acid. Furthermore, permanganate and other persalts, including peroxides such as hydrogen, can take the place of the aforementioned oxidizing agents.
The keto compounds formed can be isolated with the aid of ketone reagents, such as B. semicarbazide, hydroxylamine, phenylhydrazine and others or with the aid of fractional crystallization or the like. The new compound can advantageously be recrystallized from ethyl acetate and melts at 192-193 C.
As such, it can be used therapeutically, but it can also be used as an intermediate product for the manufacture of other therapeutically valuable substances.
<I> Example: </I> 3.5 g of 17-methyl-androstandiol-3-17-mono-aoetat-17 are dissolved in 100 cm 'of glacial acetic acid and a solution of 1.3 g of chromic anhydride in 20 cm' 90% acetic acid was added at room temperature. After the reaction mixture has been left to stand for 1 day, it is poured into water and extracted with ether. The ethereal solution is washed with alkali lye and water, freed from the water and evaporated to dryness.
After recrystallization of the residue from dilute alcohol, the acetate of 17-llethyl-androstanol-17-one-3 is obtained. The 17-pellet, # rl-androstanol-17-one-3 is made from the acetate by saponification.
