Description
Verfahren zur Darstellung eines neuen Esters. Es wurde gefunden, dass man zu neuen Estern von gesättigten odeT ungesättigten Oxyketonen vom Typus des Androstanol- (17)-on-(3) gelangen kann, wenn man diese Oxyketone mit solchen acylierenden Reagen zien behandelt,
die neben der zur Acylierung dienenden Gruppe noch eine zur Salzbildung befähigte oder eine hierin überführbare Gruppe enthalten.
Geeignete acylierende Reagenzien sind z. B. Säurechloride, Säureaahydride,wieBernstein- eäureanhydrid, Maleinsäureanhydrid, Phthal- säureanhydrid, Chlorsulfonsäure, Phosphor oxyohlorid und & ngleichen. Als Oxyketone kommen insbesondere in. Frage z.
B. Androstanol-(17)-on-(3), 17-Me- thyl-androstanol-(17)-on-(3), A4,5-Androste- nol-(17)-on-(3), 04,5-17-Methyl-androstenol- (17)-on-(3), oder deren Stereoäsomeren.
Gegenstand des vorliegenden Patentes bildet ein Verfahren zur Darstellung eines neuen Esters, welches dadurch gekennzeich net ist, dass man auf A4,5-Androstenol-(17)- on-(3) ein @Suocinylierungsmttel einwirken lässt.

Process for the preparation of a new ester. It has been found that new esters of saturated or unsaturated oxyketones of the androstanol- (17) -one- (3) type can be obtained if these oxyketones are treated with such acylating reagents,
which, in addition to the group used for acylation, also contain a group capable of salt formation or a group which can be converted therein.
Suitable acylating reagents are, for. B. Acid chlorides, acid aahydrides, such as amber anhydride, maleic anhydride, phthalic anhydride, chlorosulfonic acid, phosphorus oxychloride and the like. Particularly suitable oxyketones are.
B. Androstanol- (17) -one- (3), 17-methyl-androstanol- (17) -one- (3), A4,5-androstenol- (17) -one- (3), 04,5-17-methyl-androstenol- (17) -one- (3), or their stereoisomers.
The subject of the present patent is a process for the preparation of a new ester, which is characterized in that a suocinylation agent is allowed to act on A4,5-androstenol- (17) -on- (3).
The 04,5-Andrastenol- (17) - on - (3) - monobernstones obtained in this way, acid esters of the formula
