Description

  

  Verfahren zur Darstellung einer     d5-ungesättigten        3-epi-Ogyyerbindung    der       Cyclopentano-hydrophenanthrenreihe.       Es     wurde    :gefunden,     dass    man zu einer       ungesättigten        3-epi-Oxyverbindung    der       Cyclopentano-hydrophenanthrenreihe    .gelan  gen     kann,,    wenn     man    die     3-Ketogruppe    von       A'-Androstendion-3,

  17        unter        Erhaltung    der       Doppelbindung        in    neutralem     Medium        zur          \Cärbinolgruppe    reduziert.  



       Die        Reduktion    kann z.     .B.    auf     kataly-          tischem    Wege mit     Wasserstoff    in     Gegenwart     edler und unedler Metalle oder     Metalloxyde     wie Platin,     Platinoxyd,        Nickel,    Kobalt oder  Metallgemischen mit     und    ohne Träger in       ,neutralen        Lösungsmitteln    oder auch mit Alu  miniumamalgam vorgenommen werden.

       Zur          Abtrennung    der     erhaltenen        epi-Verbindung     von ihren     Isomeren        verwendet    man zweck  mässig     Ikgitonin        und,dergl.    oder bedient sieh  der fraktionierten     Kristallisation        geeigneter     Derivate.  



  Das verfahrensgemäss gewonnene     ds-3-epi-          Ogy-androstenon-(17)        bildet    Kristalle vom  F.<B>218'</B>     korr.       Die neue Verbindung soll therapeutische  Verwendung finden.  



  <I>Beispiel:</I>  1 Teil     A'-Androstendion-3,17    wird     in,    10  Teilen 9-5     %igem    Äthylalkohol gelöst und  unter Zusatz von 1 Teil eines aktiven     Nickel-          katalysators    bei     Zimmertemperatur    ohne     An-          wendung    eines     'Überdruckes    mit     Wasserstoff          geschüttelt.    Nach Aufnahme von 1     Mol          Wasserstoff    wird die Hydrierung unter  brochen.

   Man     filtriert,    fügt eine     alkoholische          Digitoninlösung        hinzu    und verdampft im  Vakuum den Alkohol. Den     Rückstand     extrahiert man mit Äther. Der ätherlösliche  Teil wird     aus    Äther oder     Essigester        umkri-          stallisiert,    wobei man das bei<B>218'</B>     korr.          schmelzende        d6-3-epi-O$yandrostenon-(17)     erhält.

   Das in üblicher Weise     bereitete        Acetat     schmilzt     bei        1,73,5-174,5'    .korr.



  Process for the preparation of a d5-unsaturated 3-epi-ogyyerbond of the cyclopentano-hydrophenanthrene series. It has been found that an unsaturated 3-epi-oxy compound of the cyclopentano-hydrophenanthrene series can be reached if one uses the 3-keto group of A'-androstenedione-3,

  17 is reduced to the Carbinol group in a neutral medium while maintaining the double bond.



       The reduction can e.g. .B. be carried out catalytically with hydrogen in the presence of noble and base metals or metal oxides such as platinum, platinum oxide, nickel, cobalt or metal mixtures with and without carriers in neutral solvents or with aluminum amalgam.

       To separate the epi-compound obtained from its isomers one uses appropriately Ikgitonin and, the like. or use the fractional crystallization of suitable derivatives.



  The ds-3-epi-Ogy-androstenon- (17) obtained according to the process forms crystals of F. <B> 218 '</B> corr. The new compound should find therapeutic use.



  <I> Example: </I> 1 part of A'-androstenedione-3,17 is dissolved in 10 parts of 9-5% ethyl alcohol and with the addition of 1 part of an active nickel catalyst at room temperature without the use of a ' Shaken with hydrogen at overpressure. After the absorption of 1 mol of hydrogen, the hydrogenation is interrupted.

   It is filtered, an alcoholic digitonin solution is added and the alcohol is evaporated off in vacuo. The residue is extracted with ether. The ether-soluble part is recrystallized from ether or ethyl acetate, with <B> 218 '</B> corr. melting d6-3-epi-O $ yandrostenon- (17) receives.

   The acetate prepared in the usual way melts at 1.73.5-174.5 '.korr.
