Abstract

Novel D 1,6 - 16a - alkyl - progesterones which may also contain a 6-alkyl substituent are prepared by dehydrogenation (e.g. by halogenation and dehydrohalogenation or with selenium dioxide or a quinone having an oxidation-reduction potential of less than -0.5v. or microbiologically with Corynebacterium simplex) of the corresponding D 4-, D 1,4- or D 4,6-steroids.
