Description

  

  Verfahren     zur    Darstellung     eines        ungesättigten        Alkohols.       Gegenstand der vorliegenden Erfindung  bildet ein Verfahren zur Darstellung eines  ungesättigten Alkohols, welches dadurch ge  kennzeichnet ist, dass man auf     d5,s-3-epi-Oxy-          androstenon-(17)    Wasserstoff in Gegenwart  von Metallkatalysatoren in einem neutralen  organischen Lösungsmittel einwirken lässt.  



  Das so gewonnene     d5,s-3-epi-Oxy-17-trans-          oxy-androsten    bildet Kristalle vom F.207  bis 208  . Sein     Diacetat    hat den F. 155 bis       155,50.     



  Die neue Verbindung soll therapeutische  Verwendung finden oder als Zwischenprodukt  zur Herstellung therapeutisch wirksamer Ver  bindungen dienen.    <I>Beispiel:</I>    1,6 Teile     d5,1-3-epi-Oxy-androstenon-(17),     gelöst in 250 Teilen 95      /oigem    Äthylalkohol,  werden nach Zusatz von 1,2 Teilen eines  aktiven Nickelkatalysators bei Zimmertempe  ratur mit Wasserstoff geschüttelt. Die für  1     Mol    berechnete Menge Wasserstoff ist nach    wenigen Stunden aufgenommen. Der Kataly  sator wird     abfiltriert    und die Lösung einge  dampft.

   Das so erhaltene     d5,s-3-epi-Oxy-17-          trans-oxy-androsten    kann aus Essigester um  kristallisiert und/oder im Hochvakuum bei  etwa<B>1500</B> sublimiert werden.  



  Die Reduktion kann auch in Gegenwart  eines andern unedlen oder edlen     Metallkataly-          sators    wie z. B. Platinoxyd vorgenommen  werden.



  Process for the preparation of an unsaturated alcohol. The present invention provides a process for the preparation of an unsaturated alcohol, which is characterized in that d5, s-3-epi-oxyandrostenone- (17) hydrogen is allowed to act in the presence of metal catalysts in a neutral organic solvent.



  The d5, s-3-epi-oxy-17-trans-oxy-androsten thus obtained forms crystals from F.207 to 208. Its diacetate has a F. 155 to 155.50.



  The new compound should find therapeutic use or serve as an intermediate for the preparation of therapeutically effective compounds. <I> Example: </I> 1.6 parts of d5,1-3-epi-oxy-androstenone- (17), dissolved in 250 parts of 95% ethyl alcohol, are added after adding 1.2 parts of an active nickel catalyst Room temperature shaken with hydrogen. The amount of hydrogen calculated for 1 mol is absorbed after a few hours. The catalyst is filtered off and the solution is evaporated.

   The d5, s-3-epi-oxy-17-trans-oxy-androstene thus obtained can be crystallized from ethyl acetate and / or sublimed in a high vacuum at about 1500.



  The reduction can also be carried out in the presence of another non-noble or noble metal catalyst such as B. platinum oxide are made.
