Steroids. Part XXXVI. Some 13,17-secoandrostanes
Abstract
17-Hydroxyimino-5α-androstane and 3β-acetoxy-17-hydroxyiminoandrost-5-ene, when treated with thionyl chloride, give 17-oxo-17a-aza-D-homo-compounds formed by Beckmann rearrangement, together with 13,17-seco-13(18)-en-17-onitriles (and derived 13ξ-chlorides and 13ξ-ols), formed by ‘second-order’ Beckmann cleavage.
