Abstract
Esters of saturated or unsaturated polynuclear cyclic oxyketones of the type of androstane-3-one-17-ol are prepared by treating the oxyketone with an acylating agent having more than two carbon atoms and which does not contain a group having a tendency to salt formation or capable of conversion into a salt forming group. The preferred acylating agents are fatty acids containing from 3--10 carbon atoms, such as propionic acid, butyric acid, valerianic acid, capric acid, benzoic acid and crotonic acid. Examples of suitable oxyketones are testosterone, dihydrotestosterone, 17-methyl-testosterone, and 17-methyl-dihydrotestosterone. In examples: (1) testosterone is treated with propionic acid anhydride in the presence of dry pyridine; (2) testosterone is treated in pyridine solution with n-butyric acid anhydride; (3) testosterone is treated in pyridine solution with iso-butyric acid anhydride; (4) testosterone is treated in pyridine solution with n-valerianic acid chloride; (5) testosterone and capric acid are heated at 300 DEG C. in an atmosphere of nitrogen; (6) testosterone is treated in pyridine solution with benzoyl chloride; (7) dihydrotestosterone is treated in pyridine solution with propionic acid anhydride. Instead of pyridine, another tertiary base such as dimethylaniline may be used. Other compounds mentioned as being prepared according to the present invention are androstane-3-one-17-trans-ol-hexahydrobenzoate, and androstane-3-one-17-cisol-hexahydrobenzoate.
