were the parent ketone and 17-oxa-5α-androstan-16-one, accompanied by low yields of three isomeric lactams: 17-aza-5α-androstan-16-one, 16-aza-5α-androstan-17-one, and 17-aza-5α,13α-androstan-16-one. These three are the same lactams formed in the photo-Beckmann rearrangement of the corresponding oxime, D-nor-5α-androstan-16-one oxime. Their formation from the acetylhydrazone may have some mechanistic significance

D-nor-5α-androstan-16β-carbonyl chloride, a steroidal cyclobutanecarbonyl chloride, with m-chloroperbenzoic acid leads via rearrangement to a C-homo-D-bisnor-steroid. In contrast, the 16α-isomer with m-chloroperbenzoic acid afforded the corresponding stable acyl aroyl peroxide which underwent competitively a carboxy-inversion reaction and the migration of the 13β-methyl group upon reflux in benzene
