Abstract
Novel 2 - alkyl - 1,11a - oxido - d 1,4 - 3 - keto steroids of the general formula <FORM:1082953/C2/1> wherein R is a lower alkyl group containing 1-4 carbon atoms, R11 is hydrogen or a lower alkyl group containing 1-4 carbon atoms and R1 is a keto group (in which case no R11 substituent is present), free hydroxyl group or a hydroxyl group esterified with an aliphatic, cycloaliphatic or araliphatic carboxylic acid containing 1-12 carbon atoms are obtained by subjecting a 2-halo-2-alkyl-1a , 11a -oxido-d 4-keto steroid of the formula <FORM:1082953/C2/2> to dehydrohalogenation.
