摘要

An efficient synthesis from adrenosterone or 11α-hydroxytestosterone of 17β-hydroxy-11- aza-5α-androstan-3-one, the 11-aza analogue of dihydrotestosterone, is described. For the elaboration of the 11-aza structure, a pathway implying a Curtius-type rearrangement of a 9, 11-seco 9-oxo 11-acid was employed.
