Description
Verfahren zur Herstellung einer neuen Verbindung der Cyclopentanopolyhydro- phenanthren-Reihe. Es wurde gefunden, dass man zu einer im Ring C ungesättigten Verbindung der Cyclo- pentanopolyhydrophenanthren - Reihe gelan gen kann, wenn man einen 3-Keto-bisnor- cholansäure-methylester, der im Ring C in 12-Stellung einen zusammen mit einem be nachbarten Wasserstoffatom abspaltbaren Sub- stituenten aufweist,
mit diesen Substituenten unter Bildung einer Doppelbindung abspal tenden Mitteln behandelt.
Der 12 ständige, zusammen mit einem be nachbarten Wasserstoffatom abspaltbare Sub- stituent des Ausgangsstoffes kann eine freie Hydroxylgruppe oder eine beispielsweise durch Carbonsäuren, wie Essig-, Propion- oder Benzoesäure, durch Sulfonsäuren, Halo- genwasserstoffsäuren oder Xanthogensäuren veresterte Hydroxylgruppe sein.
Die Abspaltung dieses Substituenten unter Hydroxylgruppe unter der Einwirkung von Mineralsäuren, vorzugsweise in Lösungsmit teln, wie Eisessig, Alkohol, Dioxan und der gleichen, von Phosphoroxychlorid, Bisul- faten, von Ameisensäure, Oxalsäure, von Säureanhydriden, wie Acetanhydrid oder Phosphorpentoxyd, oder durch die Einwir kung von Katalysatoren, wie Jod- oder Car- bonsäure-Salzen, abspalten.
Eine veresterte Hydroxylgruppe wird ausser durch die ge nannten Mittel vorzugsweise auch mit Alka lien, Erdalkalien, Carbonaten, organischen Basen, wie Pyridin, Dimethylanilin usw., ab gespalten. An Stelle oder in Kombination mit den genannten Mitteln lässt sich auch erhöhte Temperatur und/oder verminderter Druck an wenden. Gegebenenfalls arbeitet man auch in Gegenwart indifferenter Gase.
Statt aus Halogenwasserstoffsäureestern direkt Ha logenwasserstoff abzuspalten, kann man das Das neue Verfahrensprodukt, der d11.12_3- Keto -bisnor - cholensäure - methylester vom F. 122-123 , soll als Zwischenprodukt zur Herstellung therapeutisch wertvoller Pro dukte dienen.
<I>Beispiel:</I> 3-Keto-12 - (anthrachinon-3-carboxy)-bis- norcholansäure-methylester (erhalten durch energische Acetylierung von Bisnor-desoxy- cholsäure-methylester zum entsprechenden 3,12-Diacetat, partielle Verseifung zum 12- Monoacetat,. Oxydation zum 3-Keto-12-acet- oxy-ester,
Verseif ung zum 3-Keto-12-oxy- ester und anschliessende Umsetzung mit An thrachinon - ss - carbonsäurechlorid) wird im Hochvakuum bei 0,1 mm auf 300 Metall badtemperatur erhitzt, unter gleichzeitigem Einleiten von Kohlendioxyd durch die feine Kapillare. Nachdem der Kolbeninhalt über destilliert ist, wird das Destillat mit Lauge in neutrale und alkalilösliche Anteile zerlegt.
Aus ersteren erhält man den d11.12-3_Keto- bisnorcholensäure-methylester der Formel
EMI0002.0029
Er lässt sich zweclzmässig durch Chromato- graphie an Aluminiumoxyd reinigen und kri stallisiert dann in farblosen Plättchen vom F. 122-1230. An Stelle des 12-Anthrachinon-ss-carbon- säureesterskann auch das entsprechende Ben- zoat verwendet werden. Dasselbe Produkt erhält man ferner z.
B. durch Erhitzen des 12-Tosylates oder -1ATesylates mit Collidin oder Pyridin.
Process for the production of a new compound of the cyclopentanopolyhydrophenanthrene series. It has been found that a compound of the cyclopentanopolyhydrophenanthrene series which is unsaturated in the C ring can be obtained if a methyl 3-keto-bisnorcholanoate is used which has one in the 12-position in the C ring and one adjacent Has substituents that can be split off hydrogen atom,
treated with these substituents to form a double bond cleaving agents.
The 12 permanent substituent of the starting material which can be split off together with an adjacent hydrogen atom can be a free hydroxyl group or a hydroxyl group esterified, for example, by carboxylic acids, such as acetic, propionic or benzoic acid, by sulfonic acids, hydrohalic acids or xanthogenic acids.
The elimination of this substituent under the hydroxyl group under the action of mineral acids, preferably in solvents such as glacial acetic acid, alcohol, dioxane and the like, of phosphorus oxychloride, bisulfates, of formic acid, oxalic acid, of acid anhydrides such as acetic anhydride or phosphorus pentoxide, or by the The effects of catalysts such as iodine or carboxylic acid salts are split off.
An esterified hydroxyl group is not only cleaved by the agents mentioned, but also preferably with alkali, alkaline earths, carbonates, organic bases such as pyridine, dimethylaniline, etc., from. Instead of or in combination with the agents mentioned, it is also possible to use increased temperature and / or reduced pressure. You may also work in the presence of inert gases.
Instead of splitting off hydrogen halide directly from hydrohalic acid esters, the new process product, the d11.12_3-keto-bisnor-cholenic acid methyl ester of F. 122-123, is intended to serve as an intermediate in the manufacture of therapeutically valuable products.
<I> Example: </I> 3-Keto-12 - (anthraquinone-3-carboxy) -bis-norcholanic acid methyl ester (obtained by vigorous acetylation of bisnor-deoxycholic acid methyl ester to the corresponding 3,12-diacetate, partial Saponification to 12-monoacetate, oxidation to 3-keto-12-acetoxy-ester,
Saponification to 3-keto-12-oxy ester and subsequent reaction with anthrachinone - ss - carboxylic acid chloride) is heated in a high vacuum at 0.1 mm to a metal bath temperature of 300 mm, while simultaneously introducing carbon dioxide through the fine capillary. After the contents of the flask have distilled over, the distillate is broken down into neutral and alkali-soluble fractions with lye.
The d11.12-3_Keto-bisnorcholenic acid methyl ester of the formula is obtained from the former
EMI0002.0029
It can be purified by chromatography on aluminum oxide and then crystallizes in colorless platelets of F. 122-1230. The corresponding benzoate can also be used instead of the 12-anthraquinone-β-carboxylic acid ester. The same product is also obtained e.g.
B. by heating the 12-tosylate or -1ATesylates with collidine or pyridine.
