Description

  

  Verfahren zur Darstellung eines Alkohols der     Cyclopentanopolyhydrophenanthren-Reihe.       Es wurde gefunden, dass man zu einem Al  kohol der     Cyclopentanopolyhydrophenanthren-          Reihe    gelangen kann, wenn man auf das  Dioxyd von     d5,E-3-Acetoxy-17-äthenyl-andro-          sten    der Formel  
EMI0001.0006     
    Mittel einwirken lässt, die befähigt sind, die       Äthylenoxydbindungen    reduktiv     aufzuspalten.     



  Das so gewonnene     Pregnan-3,5,20-triol-          3-acetat    der Formel    bildet farblose Kristalle.    Die reduktive Aufspaltung der     Oxydringe     kann in an sich bekannter Weise, z. B. mit  tels Amalgamen;     Alkoholaten    wie     Aluminium-          oder        Magnesiumalkoholat    und sekundären       Alkoholen,        Alkahmetallen    und     Alkoholen,     mittels katalytisch, beispielsweise durch Me  talle, angeregtem     Wasserstoff,    auf elektroly  tischem oder biochemischem Wege erfolgen.  



  Die neue Verbindung soll therapeutische  Verwendung     finden    oder als Zwischenprodukt  zur Herstellung therapeutisch wertvoller Ver  bindungen dienen.  



       Beispiel:     1 Teil des Dioxyds von     45,1-3-Acetoxy-          17-äthenylandrosten    der Formel  
EMI0001.0024     
         wird    in     Eisessiglösung    mit     Palladiumschwarz     als     Katalysator    hydriert, bis die für 2 Äqui-  
EMI0001.0029     
           valente    berechnete Menge Wasserstoff aufge  nommen ist. Dann filtriert man vom Kataly  sator ab, verdünnt das Filtrat mit Wasser  und schüttelt mit Äther aus.

   Aus dem Rück  stand der gewaschenen und getrockneten  Ätherlösung gewinnt man nach dem     'Um-          kristallisieren    aus Alkohol das     Pregnan-3,5,':.0-          triol-3-acetat    der Formel  
EMI0002.0006     
    in Form farbloser Kristalle.



  Process for the preparation of an alcohol of the cyclopentanopolyhydrophenanthrene series. It has been found that an alcohol of the cyclopentanopolyhydrophenanthrene series can be obtained if one of the formula d5, E-3-acetoxy-17-ethhenyl-andro- sten on the dioxide
EMI0001.0006
    Allow agents to act that are capable of reductively splitting the ethylene oxide bonds.



  The pregnane-3,5,20-triol-3-acetate of the formula obtained in this way forms colorless crystals. The reductive splitting of the oxide rings can be carried out in a manner known per se, for. B. with amalgams; Alcoholates such as aluminum or magnesium alcoholate and secondary alcohols, alkali metals and alcohols are carried out by means of catalytic means, for example by metals, excited hydrogen, by electrolyte tables or biochemical means.



  The new compound should find therapeutic use or serve as an intermediate for the preparation of therapeutically valuable compounds.



       Example: 1 part of the dioxide from 45,1-3-acetoxy-17-ethenyl rust of the formula
EMI0001.0024
         is hydrogenated in glacial acetic acid solution with palladium black as a catalyst until the
EMI0001.0029
           equivalent calculated amount of hydrogen is taken up. Then the catalyst is filtered off, the filtrate is diluted with water and extracted with ether.

   The residue of the washed and dried ether solution is obtained, after recrystallization from alcohol, the Pregnan-3,5, “: 0-triol-3-acetate of the formula
EMI0002.0006
    in the form of colorless crystals.
