- W1990458220 abstract "Bei der Oxidation von 3β-Acetoxy-5α-androstan-17-on (1) mit Chromsaureanhydrid in Eisessig werden entgegen fruheren Vorstellungen nahezu wahllos alle vorhandenen CH-Bindungen angegriffen. Daneben wird auch der Ring D abgebaut. Es entsteht so das 3β-Acetoxy-(des-D)-5α,13α-androstan-14-on (4) und das 3β-Acetoxy-5α-hydroxy-(des-D)-13α-androstan-14-on (5). Aus dem Gemisch der Oxidationsprodukte wurde ferner neben dem bereits bekannten Hydroxyderivat von 1, dem 3β-Acetoxy-5α-hydroxy-androstan-17-on (2), das 3β-Acetoxy-14β-hydroxy-5α-androstan-17-on (3) isoliert.On the Chromic Anhydride Oxidation of 3β-Acetoxy-5α-androstan-17-one, II1)Contrary to earlier reports nearly all available CH bonds are attacked in the course of the oxidation of 3β-acetoxy-5α-androstan-17-one (1) with chromic anhydride in glacial acetic acid. Moreover, the D ring also undergoes degradation. Thus 3β-acetoxy-(de-D)-5α,13α-androstan-14-one (4) and 3β-acetoxy-5α-hydroxy-(de-D)-13α-androstan-14-one (5) are formed as degradation products. Apart from the known hydroxy derivative of 1, namely 3β-acetoxy-5α-hydroxyandrostan-17-one (2), 3β-acetoxy-14-hydroxy-5α-androstan-17-one (3) was also isolated from the mixture of oxidation products." @default.
