Beckmannrearrangement of the geometrical isomer of 5α-androstanolone oximes gives the 3-aza-17β-hydroxy-A-homo-5α-androstan-4-one and the 4-aza-17β-hydroxy-A-homo-5α-androstan-3-one. These lactams were converted to the corresponding ketones by Jones reagent oxidation. Treatment with hydroxylamine produced the corresponding ketoximes. Beckmannrearrangement of the ketoximes generated the diaza compounds
