Abstract
Preparation process of 21-acyloxy- δ 9 (11) -teroes of the pregnan series, characterized in that a dihydroxysteroid 9 α or 11 β, corresponding is dissolved in an organic base, and it is reacted with a carboxylic acid anhydride and a dehydrating reagent, or with an organic acid chloride at low temperature and then, after esterification of the hydroxyl group. The reaction mixture is heated more or less to room temperature in order to complete the evolution of 11 β - oh. (Machine-translation by Google Translate, not legally binding)
