The photolysis of androsterone oxime and 13α-androsterone oxime affords isomeric lactams with and without the original configuration of the C-13 substituent of the starting oxime, although there were poor yields and no products due to photo-Beckmann fission. The formation of an epimeric pair of lactams from an oxime is at variance with our previous results on the photolysis of 5α- and 5β-cholestan-6-one oximes, in which the stereochemical integrity of the terminus of the migrating carbon in the photo-Beckmann rearrangement was observed. The implication of the present results for the migration step of the photo-Beckmann rearrangement is discussed.
