Abstract

The invention comprises 4,5-epoxy-9b ,10a -steroids of the general formula <FORM:1106100/C2/1> wherein R1 represents a hydroxy group and R2 represents a hydrogen atom or an alkyl group containing from 1-5 carbon atoms or R1 and R2 together represent a keto group and wherein the broken lines denote a -configuration. These compounds are obtained by treating the corresponding 4-dehydro-9b ,10a -steroid with hydrogen peroxide in the presence of alkali.
