Oxidation of some conjugated diene steroids by hydrogen peroxide, catalysed by methyltrioxorhenium

摘要

The oxidation of some conjugated diene steroids, namely Delta(4.6)-, Delta(5.7)-, Delta(7.9(11))- and Delta(7.14)-steroids, with hydrogen peroxide in the presence of catalytic amounts of methyltrioxorhenium (MTO) at room temperature gives unsaturated 1,2- or 1,4-diols, possibly derived from allylic epoxides, and products of secondary reactions.
