Description

  

  Verfahren zur Darstellung einer     Carbonylverbindung    der       Cyclopentanopolyhydrophenanthren-Reihe.       Es wurde gefunden, dass man überraschen  derweise zu dem bekannten     Methyl-testoste-          ron    der Formel  
EMI0001.0005     
    gelangen kann, wenn man einen     d5,s-17-          Methyl-        androsten-    3,17-     diol-    3     -triaryl-methyl-          äther    einer     thermischen    Spaltung     unterwirft.     



  Verfahrensgemäss erhitzt man den Aus  gangsstoff auf höhere Temperatur, z. B. auf  etwa 200-350  . Die Reaktion kann gegebe  nenfalls im     Vakuum,    unter Druck, in Gegen  wart     inerter    Gase, wie z. B.     Stickstoff,    Koh  lendioxyd, und auch in Gegenwart eines festen  oder flüssigen Verdünnungsmittels vorgenom  men werden. Hierbei ist die Verwendung    solcher     Verdünnungsmittel    von     Vorteil,    welche  die thermische     Spaltung    katalytisch begün  stigen, d. h. die     Spaltungstemperatur    herab  setzen.

   Es seien als solche Verdünnungsmittel  beispielsweise Metalle,     Metalloxyde,    Metall  salze, wie Kupferpulver,     Aluminiumoxyd,     Zinkoxyd und     Bariumchlorid    genannt. Als  flüssige Verdünnungsmittel kommen z. B.  hochsiedende     Kohlenwasserstoffe        in    Frage.  



  Die Reaktion lässt sich durch das nach  folgende generelle Formelbild veranschauli  chen  
EMI0001.0026     
    woraus hervorgeht, dass neben der     gewünsch-.          ten        Carbonylverbindung        Triarylmethan    ent  steht.  



  Zur Abtrennung der verfahrensgemäss ent  stehenden     Carbonylverbindung    dienen an sich      bekannte Trennungsmethoden, wie z. B. die       fraktionierte    Destillation, Sublimation     bezw.          Kristallisation,    Umsetzung mit     Ketonreagen-          zien    oder andere     Reinigungs-        bezw.    Tren  nungsverfahren.  



  Die in Frage     kommenden        Triarylmethyl-          äther    können z. B. die folgenden     Triarylme-          thylreste    enthalten:     Triphenylmethyl-,        Tri-          tolylmethyl-,        Tri-(biphenyl)-methyl-,        Trinaph-          thylmethyl-,    gemischt substituierte     Triaryl-          methyl-Reste    und dergleichen.  



  Gegenüber bekannten Verfahren zur Her  stellung von     Ketonen    der     Cyclopentanopoly-          hydrophenanthren-Reihe    weist das vorliegende  den Vorteil grosser Einfachheit auf, bei guten  Ausbeuten, wie Versuche ergaben.  



  Die auf diese Weise erhaltene bekannte  Verbindung soll therapeutische Verwendung  finden oder als Zwischenprodukt zur Herstel  lung therapeutisch verwendbarer     Stoffe    dienen.         Beispiel:     10 Teile     d5-E-17-Methyl-androsten-3,17-          diol-3-triphenylrnethyläther    (hergestellt z. B.  aus     17-Methyl-androsten-3,17-diol    und     Tri-          phenylchlormethan    in     Pyridin)    werden mit  20 Teilen Kupferspänen gemischt und im  Vakuum auf 250 - 300       erhitzt.    Das erhaltene       Sublimat    wird z.

   B. durch fraktionierte Kri  stallisation oder mit Hilfe von     Ketonreagen-          zien    wie     Girard-Reagens    in     Triphenylmethan     und     17-Methyl-testosteron    getrennt.  



  Als     Ausgangsstoff    kann man     zweckmässig     z. B. auch     d5,e-17-Metliyl-androsten-3,17-diol-          3-trinaphthylmethyläther    verwenden.



  Process for the preparation of a carbonyl compound of the cyclopentanopolyhydrophenanthrene series. It has been found that surprisingly, the well-known methyl testosterone of the formula
EMI0001.0005
    can be achieved if a d5, s-17-methyl androstene-3,17-diol-3-triaryl methyl ether is subjected to thermal cleavage.



  According to the method, the starting material is heated to a higher temperature, eg. B. to about 200-350. The reaction can, if necessary, in vacuo, under pressure, in the presence of inert gases, such as. B. nitrogen, Koh lendioxyd, and also in the presence of a solid or liquid diluent vorgenom men. The use of diluents which catalytically favor the thermal cleavage is advantageous here, i.e. H. reduce the cleavage temperature.

   Examples of such diluents are metals, metal oxides, metal salts such as copper powder, aluminum oxide, zinc oxide and barium chloride. As a liquid diluent, for. B. high-boiling hydrocarbons in question.



  The reaction can be illustrated by the following general formula
EMI0001.0026
    which shows that in addition to the desired. ten carbonyl compound triarylmethane is formed.



  To separate the resulting carbonyl compound according to the process, known separation methods such. B. the fractional distillation, sublimation BEZW. Crystallization, reaction with ketone reagents or other cleaning resp. Separation procedure.



  The triarylmethyl ethers in question can, for. B. contain the following triaryl methyl radicals: triphenylmethyl, tri tolylmethyl, tri- (biphenyl) methyl, trinaphthylmethyl, mixed substituted triaryl methyl radicals and the like.



  Compared to known processes for the manufacture of ketones of the cyclopentanopolyhydrophenanthrene series, the present one has the advantage of great simplicity and good yields, as tests have shown.



  The known compound obtained in this way is intended to be used in therapy or to serve as an intermediate for the preparation of therapeutically useful substances. Example: 10 parts of d5-E-17-methyl-androstene-3,17-diol-3-triphenylmethylether (prepared for example from 17-methyl-androstene-3,17-diol and triphenylchloromethane in pyridine) are added 20 parts of copper chips mixed and heated to 250-300 in a vacuum. The sublimate obtained is z.

   B. by fractional crystallization or with the help of ketone reagents such as Girard reagent separated into triphenylmethane and 17-methyl-testosterone.



  The starting material can be conveniently z. B. also use d5, e-17-methyl-androstene-3,17-diol-3-trinaphthylmethyl ether.
