Abstract

Anti-androgenic 11-beta, 17 alpha-dihydroxy-A-nor-progesterone and its esters. G3A. Are new cpds. of formula (I) (where R and R' are H or acyl, pref. derived from 12 C hydrocarbon carboxylic acids). Prepared by subjecting 17 alpha-hydroxy-A-nor-progesterone (II) to the action of a microorganism of the genus Curvularia (pref. C. Lumata) and opt. acylating the resulting (I; R=R'=H) with a carboxylic acid anhydride (pref. Ac20) in the presence of a catalytic amount of HCl04 and opt. converting the resulting (I; R=R'=acyl) into (I; R=acyl, R'=H) by treating with aqs. soln. of a weak base (e.g. Na2CO3, K2CO3).
