Description

  

  Verfahren zur Darstellung eines tertiären     Carbinols    der     Cyelopentanopolyhydrophen-          anthren-Reihe.       Die vorliegende Erfindung     betrifft    ein  Verfahren zur Darstellung von     Äthinyl-17-          androstendiol-3.17.     



  Das Verfahren ist dadurch gekennzeich  net, dass man     d5,E-Androstenol-3-on-17    mit  metallorganischen Verbindungen des Ace-         tylens    zur Umsetzung bringt und das gebil  dete Umsetzungsprodukt durch Einwirkung       hydrolysierender    Mittel spaltet.  



  Die folgenden Formelbilder mögen zur  Veranschaulichung des erfindungsgemässen  Verfahrens dienen  
EMI0001.0010     
    Das     Äthinyl-17-androstendiol-3.17    soll als  Arzneimittel oder als     Zwischenprodukt    für  die Darstellung anderer physiologisch wert  voller     Stoffe    Verwendung finden.         Beispiel:     0,7 g Magnesium, 4,6 g Brombenzol und  50 cm' Äther werden während 30 Stunden    unter ständigem Durchleiten von Acetylen  zum schwachen Sieden erwärmt. Dazu gibt  man unter Rühren, Schütteln und ständigem  Durchleiten von Acetylen eine Lösung von  0,5 g     A5,6-Androstenol-3-on-17    in 20 cm'  Äther.

   Nach 3 Tagen wird das Reaktions  gemisch mit Eiswasser versetzt, mit ver  dünnter Schwefelsäure schwach angesäuert      und mit Äther ausgezogen. Nach dem Trock  nen und Verdampfen des Äthers entfernt  man aus dem Rückstand unverändertes     Keton     mittels     Semicarbazid    und kristallisiert das       .Äthirry1-17-androstendiol-3.17    aus verdünn  tem Alkohol.  



  Der Schmelzpunkt des     Äthinyl-andro-          sterrdiol-3    .17 liegt bei ?40 0;     [a]D    = -130 0       (Dioxan).    Erhalten werden etwa 0,13 g, ausser  dem werden etwa 0,31 g     Sernicarbazon    des       Androstenolons    zurückgewonnen. Die Aus  beute beträgt somit 40     0/'o.     



  Wenn der ölige Rückstand nicht von  selbst kristallisiert, empfiehlt es sich, daraus       rnit    Silbernitrat die     schwerlöslielre    Silberver  bindung herzustellen und abzuscheiden, diese  dann mit Salzsäure wieder zu zerlegen und  für sich zur Kristallisation zu bringen.



  Process for the preparation of a tertiary carbinol of the cyelopentanopolyhydrophenanthene series. The present invention relates to a method for the preparation of ethynyl-17-androstenediol-3.17.



  The process is characterized in that d5, E-androstenol-3-one-17 is reacted with organometallic compounds of acetylene and the reaction product formed is cleaved by the action of hydrolyzing agents.



  The following formula images serve to illustrate the method according to the invention
EMI0001.0010
    Ethynyl-17-androstenediol-3.17 should be used as a medicinal product or as an intermediate for the preparation of other physiologically valuable substances. Example: 0.7 g of magnesium, 4.6 g of bromobenzene and 50 cm 'of ether are heated to a gentle boil for 30 hours while constantly passing acetylene through. A solution of 0.5 g of A5,6-androstenol-3-one-17 in 20 cm of ether is added with stirring, shaking and constant passage of acetylene.

   After 3 days, the reaction mixture is mixed with ice water, weakly acidified with dilute sulfuric acid and extracted with ether. After drying and evaporation of the ether, unchanged ketone is removed from the residue using semicarbazide and the .Äthirry1-17-androstenediol-3.17 is crystallized from dilute alcohol.



  The melting point of ethynyl-androsterrdiol-3 .17 is? 40 0; [a] D = -130 0 (dioxane). About 0.13 g are obtained, in addition about 0.31 g of sernicarbazone of androstenolone are recovered. The yield is thus 40%.



  If the oily residue does not crystallize by itself, it is advisable to use silver nitrate to produce the poorly soluble silver compound and to separate it, then to break it down again with hydrochloric acid and to crystallize it on its own.
