Description

Verfahren zur Darstellung von Acylderivaten des Dihydrofollikelhormons Nach dem Verfahren gemäß Patent 641 99,4 erhält man Acylderivate des Dihydrofollikelhormons in der Weise, daß man dieses Hormon oder seine Monoacylderivate der Einwirkung acylierender Mittel unterwirft. Gemäß vorliegender Erfindung kann man zu diesen Acylderivaten auch gelangen, wenn man die Acylderivate des Follikelhormons der Formel CI8H2202 der Einwirkung reduzierender Mittel bzw. der katalytischen Reduktion unterwirft.Process for the preparation of acyl derivatives of the dihydrofollicle hormone Acyl derivatives of the dihydrofollicle hormone are obtained by the process according to patent 641 99.4 in such a way that this hormone or its monoacyl derivatives are acylating to the action Subjects means. According to the present invention, these acyl derivatives can be added also get by using the acyl derivatives of the follicular hormone of the formula CI8H2202 subjected to the action of reducing agents or catalytic reduction.

Acylderivate des Follikelhormons wurden bereits einer Reduktion unterworfen (Butenandt, Untersuchungen über das weibliche Sexualhormon, 1934 S. 61 und 64); doch handelt es sich bei dieser Veröffentlichung um eine katalytische Hydrierung, wobei neben der vollständigen Hydrierung des aromatischen Sechsringes die Ketogruppe zur Methylengruppe reduziert wird. Dabei tritt gleichzeitig eine Entacylierung ein. Das vorliegende Verfahren stellt demgegenüber einen reinen Reduktionsprozeß dar, durch den nur die Ketogruppe der Acylderivate des Follikelhormons in die sekundäre Alkoholgruppe übergeführt wird, wobei im Gegensatz zu der Methode von Butenandt die Anzahl der Sauerstoffatome, der aromatische Kern und schließlich auch die esterartige Bindung im Molekül erhalten bleiben.Acyl derivatives of the follicle hormone have already been subjected to a reduction (Butenandt, investigations on the female sex hormone, 1934 pp. 61 and 64); however, this publication is a catalytic hydrogenation, in which, in addition to the complete hydrogenation of the aromatic six-membered ring, the keto group is reduced to the methylene group. At the same time, deacylation occurs. In contrast to this, the present process represents a pure reduction process through which only the keto group of the acyl derivatives of the follicular hormone is converted into the secondary alcohol group, in contrast to Butenandt's method, the number of oxygen atoms, the aromatic nucleus and finally also the ester-like bond in the molecule remain.

Die Reduktion erfolgt nach an sich bekannten Methoden, wie sie z. B. in Houben, »DieArbeitsrnethodederorganischenChemie«, 3, Auflage, Band II, S. 245 ff ., beschrieben sind. Es ist hierbei lediglich zu beachten, daß man solche leicht durch Vorversuche feststellbare Reduktionsbedingungen wählt, bei denen eine weitergehende Hydrierung bzw. Abspaltung der Estergruppe vermieden wird.The reduction is carried out according to methods known per se, such as those described, for. B. in Houben, "DieArbeitsrnethodederorganischenChemie", 3rd edition, Volume II, p. 245 ff., Are described. It is only necessary to ensure that reduction conditions are selected which are easily ascertainable by preliminary experiments and under which further hydrogenation or elimination of the ester group is avoided.

Die erhaltenen Reduktionsprodukte zeichnen sich gegenüber den nicht reduzierten Follikelhormonestern sowohl durch ihre höhere Wirksamkeit als auch durch höhere Löslichkeit aus, d. h. durch Faktoren, die es ermöglichen, hochkonzentrierte Lösungen dieser Präparate herzustellen, wie sie in der Therapie z. B. nach Kaufmann benötigt werden. Beispiel 1 i g Benzoylfollik-elliorinon wird in Alkohol gelöst und mit i e#eit16s nach C o n ii o r, F.a 1:-# . J, kers und Atkins, Journ. of flie Anfep CheM- SOe. 54, S. 1138, 1932, hergest Nickelchronikatalvsators versetzt. Di e duktion wird ini Autoklaven bei einer peratur von etwa i2o# durchgeführt. Nach vollendeter Reaktion wird die vom Katalysator befreite Lösung durch Linengen zur Kristallisation gebracht. Man erhält als Reaktionsprodukt das Moiiol)eiizo##ldibydrofollikelhormon der Formel C., -"1-1."03, das bei 189,51 schmilzt. Die physiologische Wirksamkeit des Präparates beträgt 15 Millionen M. E. pro Gramm, wenn inan es in (-)l gelöst iiiiiziert. Beispiel 2 2,7g Follilelliortlionacetat voni Schmelzpunkt i 16 bis 124' werden in i 5o ccin Alkohol in Gegenwart Voll 2 g eines vorreduzierten Nickelkatalysators bei i8o-' und ioo atin. mit Wasserstoff behandelt, bis die Hydrierung zum Stillstand kommt (5 Stunden). Die Auf- arbeitung erfolgt durch Abfiltration vom Ka- sator und Abdestillieren des Lösungs- .ta Iv bintels. Der Rückstand, der das rohe, phy.- t# #W-isch bereits verwendbare Hydrierungs- kt darstellt, hat keinen scharfen Skinnielzpunkt, sondern sintert bei 156' und schmilzt vollkommen erst bei 174 bis 188'. Er stellt ein Isoinerengemisch dar, das sich mit tiefblauer Fluorescenz in Schwefelsäure löst. The reduction products obtained are distinguished from the unreduced follicular hormone esters both by their higher effectiveness and by their higher solubility, i. H. by factors that make it possible to produce highly concentrated solutions of these preparations, as used in therapy for. B. are required by Kaufmann. Example 1 i g Benzoylfollik-elliorinon is made in alcohol solved and with ie # eit16s after C on ii or, Fa 1: - # . J, kers and Atkins, Journ. of flie Anfep CheM- SOe. 54, p. 1138, 1932, hergest Nickel chronicle catalogs displaced. The production is ini autoclaves at a temperature of about i2o #. When the reaction is complete, the solution freed from the catalyst is crystallized by Linengen. The reaction product obtained is the mol) eiizo ## ldibydrofollicle hormone of the formula C., - "1-1." 03, which melts at 189.51. The physiological efficacy of the product is 15 million M. E. per gram when inan it in - iiiiiziert solved l (). Example 2 2.7 g Follilelliortlionacetat voni melting point i 1 6-124 'are in i 5o CCIN g alcohol in the presence of a prereduced nickel catalyst Full 2 at i8o-' and ioo atin. with Treated hydrogen until hydrogenation comes to a standstill (5 hours). The up processing is carried out by filtering off the and distilling off the solution .ta Iv bintels. The residue that the raw, phy.- t # # W-ish already usable hydrogenation kt represents, has no sharp Skinnielz point but sinters at 156 'and melts completely only at 174 to 188 '. It represents a mixture of Isoineren that with deep blue fluorescence in sulfuric acid solves.
