Description
Verfahren zur Darstellung eines Gemisches isomerer Aeyloctahydrofollikelhormone. Gegenstand vorliegenden Patentes ist ein Verfahren zur Darstellung eines Gemisches dei, i soni eren hon oh exahydrobenzoyl octahyd ro- follikelhormone, das dadurch gekennzeichnet ist, dass man ein Gemisch der beiden isomeren Monobenzoyldihydi,ofollikelhormone mit kata lytisch erregtem Wasserstoff unter Bedin gungen behandelt,
bei denen der Benzolkern hydriert wird.
Zweckmässig geschieht die Durchführung der Hydrierung durch Zufuhr von Wasser stoff bei Gegenwart von Katalysatoren; am besten in Anwesenheit eines Lösungsmittels. <I>Beispiel:</I> ä g der Monobenzoylderivate des Dibydro- follikelhormonisomerengemisches, so wie es bei der Reduktion der Ketogruppe des e ol- likelhormons zur sekundären Alkoholgruppe erhalten wird, werden mit der gleichen Menge eines vorreduzierten Nickelkatalysa- tors (mit Zusätzen von Kupfer und Kobalt)
bei einem Wasserstoffdruck von 100 Atmo sphären im Autoklaven auf ca.<B>180'</B> erhitzt. Nach beendeter Wasserstoffaufnahme wird die vom Katalysator befreite Reaktionslösung zur Trockne abgedampft. Das erhaltene Hy- drierungsprodukt, ein Gemisch isomerer Mo nohexahydrobenzoyloctahydrofollikelhbrmone, das als Arzneimittel Verwendung finden soll, besitzt harzige Konsistenz und kann durch Verseifung in ein Gemisch isomerer Octa- hydrofollikelhormone der Formel C18H8002 übergeführt werden.
Process for the preparation of a mixture of isomeric aeyloctahydrofollicle hormones. The subject of the present patent is a process for the preparation of a mixture of the iosonic hon oh exahydrobenzoyl octahydrofollicle hormones, which is characterized in that a mixture of the two isomeric monobenzoyldihydric, ofollicular hormones is treated with catalytically excited hydrogen under conditions
in which the benzene nucleus is hydrogenated.
The hydrogenation is expediently carried out by supplying hydrogen in the presence of catalysts; best in the presence of a solvent. <I> Example: </I> ä g of the monobenzoyl derivatives of the dibydrofollicle hormone isomer mixture, as obtained in the reduction of the keto group of the oleic hormone to the secondary alcohol group, are treated with the same amount of a pre-reduced nickel catalyst (with additives of copper and cobalt)
heated to approx. <B> 180 '</B> at a hydrogen pressure of 100 atmospheres in the autoclave. After the uptake of hydrogen has ended, the reaction solution freed from the catalyst is evaporated to dryness. The hydrogenation product obtained, a mixture of isomeric monohexahydrobenzoyloctahydrofollicle hormones, which is to be used as a pharmaceutical, has a resinous consistency and can be converted into a mixture of isomeric octahydrofollicle hormones of the formula C18H8002 by saponification.
