Description
Verfahren zur Darstellung von Androstendiol-3,17-monotritylätber-3. Die vorliegende Erfindung betrifft ein Verfahren zur Darstellung von Androsten- diol-3,17-monotrityläther-3, welches dadurch gekennzeichnet ist, dass man trans-Dehydro- androsteron-3-trityläther mit einem Reduk tionsmittel behandelt, welches lediglich die Ketogruppe in die sekundäre Alkoholgruppe überführt, ohne die Ringdoppelbindung zu hydrieren.
Als besonders geeignete Reduktionsmittel haben sich alkalische Reduktionsmittel, wie zum Beispiel Alkalimetalle in Gegenwart von Alkoholen erwiesen.
<I>Beispiel 1:</I> 14,5 g trans-Dehydroandrosteron werden 21/2 Stunden auf dem Wasserbad mit 18 g Triphenylmethylchlorid (Tritylchlorid) und 50 cm' wasserfreiem Pyridin erwärmt. Das Reaktionsgemisch wird in trockenem Äther aufgenommen, filtriert und dann zur Ent fernung des Restes von Pyridinchlorhydrat reichlich mit Wasser gewaschen. Der nach Verdampfen des Äthers erhaltene Rückstand kann gegebenenfalls aus Alkohol umkristalli siert werden.
Er stellt ein weisses, kristallines Pulver vor, das bei 185 bis 186 (unkorr.) schmilzt und wenig löslich in Methanol und Äthanol, leicht löslich in andern organischen Lösungsmitteln mit Ausnahme von Petrol- äther ist.
Das Verdampfungsprodukt des Äthers wird mit oder ohne weitere Reinigung in 350 cm' kochendem Propanol gelöst und durch 20 g Natrium in einem mit Rückfluss- kühler und einer energischen Rührvorrich- tung versehenen Kolben reduziert. Wenn das Natrium aufgelöst ist, giesst man den Kol beninhalt in einen grossen Überschuss Wasser; man schüttelt mit Äther aus und wäscht die Ätherlösung mehrmals mit reinem Wasser, bis sie neutral geworden und der grösste Teil des Propanols entfernt ist.
Die ätherische Lösung hinterlä.sst nach Trocknen über Natriumsulfat und Abdamp fen des Äthers einen Rückstand, der aus einem mikrokristallinen Pulver besteht, selbst in der Siedehitze äusserst wenig löslich in Äthylalkohol und Methylalkohol ist und den 3-Monotrityläther des Androstendiols mit einem Schmelzpunkt von 226 bis 228 (un- korr.) vorstellt.
Die neue Verbindung soll als Zwischen produkt für die Herstellung wertvoller Ver bindungen mit der Wirkung der Sexual hormone Verwendung finden.
<I>Beispiel 2:</I> 2 Teile trans-Dehydroandrosteron-3-tri- tyläther werden in 30 Teilen siedendem n- Propylalkohol gelöst und portionsweise mit 2 Teilen Natrium versetzt. Das Reduktions produkt scheidet sich während der Reaktion grösstenteils als kristallinisches Pulver aus. Nach Auflösung des Natriums wird abge kühlt und 20 Teile Wasser zugegeben. Der A""-Androsten-3,17-diol-3-trityläther wird abgesaugt und mit Wasser und Alkohol ge waschen.
Er stellt ein feinkristallinisches Pulver vom Schmelzpunkt 226 bis<B>228'</B> (ua- korr.) dar. Aus dem abgetrennten Propyl- a.lkohol kann noch eine kleine Menge des Diol-tritylä,thers isoliert werden. Die Aus beute beträgt über 90 % der Theorie.
Beispiel <I>3:</I> 1,5 g trans-Dehydroandrosteron werden in einem mit Steigrohr versehenen Schliff- kölbchen mit 1,75 g sublimiertem Triphe- nylmethylehlorid, <B>1,05</B> g Triäthy lamin und 2,1 cm' trockenem Dioxan unter Rückfluh erhitzt, dann mit der zur Zerstörung des überschüssigen Triphenylmethylchlorids eben ausreichenden Menge Natriumäthylat ver setzt, kurz aufgekocht, mit Wasser zersetzt,
in Äther aufgenommen und die Reaktionspro dukte durch Abdampfen isoliert. Durch Auf nehmen in Aceton, Entfärben durch Tier- kohle und mehrfaches Umlösen durch Was serzusatz werden 2,05 g des gesuchten Tri- phenylmethyläthers (Trityiäthers) gewon nen (F. =178 ); durch weiteres Umlösen kann der Schmelzpunkt auf 185 bis 186 ge steigert werden.
1,84 g des gereinigten Triphenylmethyl- äthers (Trityläthers) werden in der Wärme in zirka 40 cm' Propanol gelöst und langsam und unter Rühren 1,7 g Natrium, unter gleichzeitigem Erwärmen, nach und nach ein getragen. Nach Verbrauch des Natriums wird noch 1/2 Stunde nacherwärmt, dann mit Was ser zersetzt, ausgeäthert und der gewaschene Äther abgedampft.
Durch Umkristallisierung aus Alkohol erhält man den Androstendiol- 3,17-monotrityläther-3 vom Schmelzpunkt 226 bis 228 (unkorr.) in Form weisser Kri stalle.
Method for the preparation of androstenediol-3,17-monotrityl ether-3. The present invention relates to a method for the preparation of androstenediol-3,17-monotritylether-3, which is characterized in that trans-dehydrosterone-3-tritylether is treated with a reducing agent which only converts the keto group into the secondary Alcohol group transferred without hydrogenating the ring double bond.
Alkaline reducing agents, such as, for example, alkali metals in the presence of alcohols, have proven to be particularly suitable reducing agents.
<I> Example 1: </I> 14.5 g of trans-dehydroandrosterone are heated for 21/2 hours on a water bath with 18 g of triphenylmethyl chloride (trityl chloride) and 50 cm of anhydrous pyridine. The reaction mixture is taken up in dry ether, filtered and then washed copiously with water to remove the remainder of the pyridine chlorohydrate. The residue obtained after evaporation of the ether can optionally be recrystallized from alcohol.
He presents a white, crystalline powder, which melts at 185 to 186 (uncorrupted) and is sparingly soluble in methanol and ethanol, slightly soluble in other organic solvents with the exception of petroleum ether.
The evaporation product of the ether is dissolved, with or without further purification, in 350 cm. Boiling propanol and reduced by 20 g of sodium in a flask equipped with a reflux condenser and a vigorous stirring device. When the sodium has dissolved, the contents of the flask are poured into a large excess of water; it is shaken out with ether and the ethereal solution is washed several times with pure water until it has become neutral and most of the propanol has been removed.
After drying over sodium sulphate and evaporation of the ether, the ethereal solution leaves a residue that consists of a microcrystalline powder, is extremely sparingly soluble in ethyl alcohol and methyl alcohol even at boiling point and the 3-monotrityl ether of androstenediol with a melting point of 226 to 228 (uncorrected).
The new compound is intended to be used as an intermediate product for the production of valuable compounds with the effects of sex hormones.
<I> Example 2 </I> 2 parts of trans-dehydroandrosterone-3-trityl ether are dissolved in 30 parts of boiling n-propyl alcohol and 2 parts of sodium are added in portions. The reduction product is largely separated out as a crystalline powder during the reaction. After the sodium has dissolved, the mixture is cooled and 20 parts of water are added. The A "" - androstene-3,17-diol-3-trityl ether is filtered off with suction and washed with water and alcohol.
It is a finely crystalline powder with a melting point of 226 to 228 '(inter alia). A small amount of the diol trityl ether can still be isolated from the propyl alcohol that has been separated off. The yield is over 90% of theory.
Example <I> 3: </I> 1.5 g of trans-dehydroandrosterone are placed in a flask provided with a riser tube with 1.75 g of sublimed triphenyl methyl chloride, 1.05 g of triethylamine and 2.1 cm 'of dry dioxane heated under reflux, then with the amount of sodium ethylate just enough to destroy the excess triphenylmethyl chloride, boiled briefly, decomposed with water,
taken up in ether and the reaction products isolated by evaporation. By taking up in acetone, decolorizing with animal charcoal and repeated dissolving by adding water, 2.05 g of the desired triphenylmethyl ether (trityi ether) are obtained (F. = 178); the melting point can be increased to 185 to 186 ge by further dissolving.
1.84 g of the purified triphenylmethyl ether (trityl ether) are dissolved in the warmth in about 40 cm of propanol and slowly and with stirring 1.7 g of sodium, with simultaneous heating, are gradually introduced. After the sodium has been used up, the mixture is heated for a further 1/2 hour, then decomposed with water, extracted with ether and the washed ether evaporated.
Recrystallization from alcohol gives androstenediol-3,17-monotrityl ether-3 with a melting point of 226 to 228 (uncorrupted) in the form of white crystals.
