Verfahren zur Darstellung eines ILeto-cyclopentano-dimethyl- tetradekaliydro-phenanthrols. Gegenstand vorliegenden Patentes ist ein Verfahren zur Darstellung eines Beta cyclopentano--dimethyl-tetra:
d.ekahydro-phen anthrols, das dadurch gekennzeichnet ist, dass, man auf eine Verbindung, welche sich vom Pregnanol-3,-on-2'0 dadurch ableitet, dass sie an Stelle der Hydroxylgruppe in 3-,Stel- lung eine durch Hydrolyse in die Hydroxyl- gruppe überführbare Gruppe, z.
B. eine Ester- oder Äthergruppe oder Halogen be sitzt, eine metallorganische Verbindung ein wirken lässt, das so erhaltene Reaktionspro- dukt mit einem wasserhaltigen Agenz zer setzt, aus dem erhaltenen tertiären Alko hol Wasser abspaltet,
die dabei erhaltene ungesäMigfie Verbindung durch Einwirkung eines Oxydationsmittels an der Kohlenstoff Kohlenstoff-Doppelbindung unter Ausbil dung einer Ket bo-ruppe spaltet und hierauf dien Hydroxylgruppe in 3-Stellung wieder herstellt.
Man kann die Wasserabspaltung vorteil haft durch physikalische Methoden, z. B, durch Erhitzen des Dialkohols im Hoch vakuum bewirken. Das gleiche Ergebnis kann aber auch mit chemischen Mitteln, z. B. durch Erhitzendes Dialkohols mit was serfreiem Kupfersulfat oder dergl., erzielt werden.
Als metallorganische Verbindung eignet sich vorzugsweise eine Magnesium-Organo- halogenverbindung, während man als Oxy- dationsmittel vorzugsweise Ozon verwendet.
Das Verfahren .gestattet auf syntheti- schem Wege, d. h. unabhängig vom Harn und andern Ausigangsmaterialien, die männ liche Sexualhormone enthalten, zu einem Produkt zu gelangen, das zur Herstellung von Präpara=ten mit Keimdrüsenhormonwir- kung Verwendung finden soll.
Das erhaltene Keto-cyclopentano-dime- thyl-tetradekahydro-phenanthrol, das soge- nannte 3-Oxyätiocholanon-17 ist in der Literatur bereits beschrieben (vergl. z. B. Helv. *im.
Acta Bd. 17, 1934, S. 19#9i6). <I>Beispiel:</I> 1 g @- @cetyl-pregnanol-(3)-oii-(?@)) wird in 50 cm.:' 3tlier gelöst, die Lösung einer Lö sung von 0,
8 g Magnesium Und 1.8 g Methy 1- jodid in G ein'' Äther zugefügt und das Re- aktionsgemiscli 3 Stunden erhitzt. Hierauf wird das Lösungtmit-tel ahdestilliert und der Rückstand weitere .3 Stunden auf dem Was serbad erwärmt, Eis und verdünnte Schwe felsäure hinzugegeben und finit. Äther extra hiert.
Nach Verdampfen des Äthers und V erseifung erhält man in Form eines schwer löslichen kristallinen Niederschlages einen tertiären Alkohol. Die Ausbeute beträgt etw=a 0,53 g.
Kocht man dieses Produkt 21''i Stunden in Eisessiglösung und erhitzt es schliesslich -ährend 15 Minuten mit Essigsäureanhyd- rid, so wird IÄ'asser abgespalten. Nach Ver dampfen des Anhydrids wird das Reaktions produkt mehrmals aus verdünntem Alkohol umkristallisiert, wobei man das Acetat des ungesättigten Alkohols erhält.
125 in.- des Aoetatec, -erden in 1 0 ein' Chloroform gelöst. und unter Eiskühlung mit Ozon behandelt. Die Lösung des Ozonids wird eine halbe Stunde mit 1.5 ein" Wasser zum Sieden erhitzt. Nach Verdampfen des Chloroforms bleibt ein kristalliner Rück- stand zurück. der nach wiederholtem 11m kristallisieren ans Methanol rein ist.. Die Ausheute beträgt etwa. 1.10 mg.
Das Acetat wird durch lialhstiindiges Er hitzen mit dreifach normaler methylalkoholi- scher KOH-Lösung verseift. Der Ketonalko- hol der Formel Cl"H.;"O@ wird nach Ansäuern der V erseifungslösung durch Wasserzusatz ausgefällt. Beim Umkrista.llisieren aus ver dünntem Alkohol erhält man das Produkt in einer Ausbeute von ungefähr<B>75</B> mg.
Process for the preparation of an ILeto-cyclopentano-dimethyl-tetradekalihydro-phenanthrol. The subject of the present patent is a process for the preparation of a beta cyclopentano - dimethyl-tetra:
d.ekahydro-phen anthrols, which is characterized in that, on a compound which is derived from pregnanol-3, -one-2'0 in that it has a 3-position instead of the hydroxyl group Hydrolysis in the hydroxyl group convertible group, z.
B. an ester or ether group or halogen, allows an organometallic compound to act that decomposes the resulting reaction product with a water-containing agent, splits off water from the tertiary alcohol obtained,
the unsaturated compound obtained in this way cleaves the carbon-carbon double bond through the action of an oxidizing agent to form a keto group and then restores the hydroxyl group in the 3-position.
You can the elimination of water advantageous by physical methods, for. B, by heating the dialcohol in a high vacuum. The same result can also be achieved with chemical agents, e.g. B. by heating the dialcohol with what serfreiem copper sulfate or the like. Can be achieved.
A magnesium-organo-halogen compound is preferably suitable as the organometallic compound, while ozone is preferably used as the oxidizing agent.
The process. Permits by synthetic means, i. H. to arrive at a product independent of urine and other starting materials that contain male sex hormones, which is to be used for the manufacture of preparations with gonadal hormone effects.
The keto-cyclopentano-dimethyl-tetradecahydro-phenanthrol obtained, the so-called 3-oxyethiocholanone-17, has already been described in the literature (see, for example, Helv. * Im.
Acta Vol. 17, 1934, p. 19 # 9i6). <I> Example: </I> 1 g @ - @ cetyl-pregnanol- (3) -oii - (? @)) Is dissolved in 50 cm .: '3tlier, the solution is a solution of 0,
8 g of magnesium and 1.8 g of methyl iodide in 1 ½ of ether are added and the reaction mixture is heated for 3 hours. The solvent is then distilled off and the residue is heated on the water bath for a further 3 hours, ice and dilute sulfuric acid are added and finite. Ether extra here.
After evaporation of the ether and saponification, a tertiary alcohol is obtained in the form of a poorly soluble crystalline precipitate. The yield is about 0.53 g.
If this product is boiled for 21 ½ hours in glacial acetic acid solution and finally heated with acetic anhydride for 15 minutes, water is split off. After the anhydride has evaporated, the reaction product is recrystallized several times from dilute alcohol, the acetate of the unsaturated alcohol being obtained.
125 in.- of Aoetatec, -erden dissolved in 1 0 a 'chloroform. and treated with ozone while cooling with ice. The solution of the ozonide is heated to the boil for half an hour with 1.5 ″ water. After the chloroform has evaporated, a crystalline residue remains. After repeated 11m crystallization of the methanol it is pure. The current amount is approximately 1.10 mg.
The acetate is saponified by long-term heating with triple normal methyl alcoholic KOH solution. The ketone alcohol of the formula Cl "H.;" O @ is precipitated after the acidification of the saponification solution by adding water. When recrystallizing from diluted alcohol, the product is obtained in a yield of about 75 mg.
