Perbenzoic Acid Oxidation of Some 3-Ketosteroids

Oxidation of 4-chlorocholest-4-en-3-one (I) with perbenzoic acid givens methyl 4-oxa-3-oxo-4-nor-5β-cholestan-5-carboxylate (IV), 3,6-dioxo-5-hydroxy-5α-cholestan-4α-yl chloride (V), 3-oxo-4-oxa-A-homo-1,4a-cholestandien-4-yl chloride (VI) and 3,4-secocholestan-2-methyl carboxy-5β-oyl chloride (VII).The 4-bromo analogue (II) of I on similar treatment provides 4a-bromo-3-oxa-A-homocholest-4a-en-4-one (VIII) and 3,4-seco-5α-cholestan-3,4-dioic acid 3-methyl ester (IX). 4β,5-Epoxy-5β-cholestan-3-one (III) under similar conditions gives 3-oxa-4aξ,5ξ-epoxy-A-homocholestane-4,6-dione (X), 4-oxa-4-nor-5-formyloxy-5α-cholestan-3-one (XI) and 5-oxo-3,5-seco-4-norcholestan-3-oic acid (XII).The structures of these products have been established by their analytical and spectral data.
