The Selective Oxidation of Protected Cholestanol derivatives using the Gif System

Oxidation of 3β,5α6β-triacetoxycholestane using the Gif system (iron cluster-metallic zinc-pyridine-aqueous acetic acid) gives, as major product, the side-chain fission ketone 3β,5α,6β-triacetoxy-5α-pregnan-20-one.The 15- and 16-keto derivatives of the parent triacetate are also formed.Comparable results are obtained in the oxidation of cholestanol acetate and of acetoxycholestan-6-one ethylene ketal.
