refluxing methylene chloride, in the presence of a small amount of water and tert-butanol, has been found to be a highly β-selective high-yield epoxidation reagent for Δ4, Δ5 and Δ7 unsaturatedsteroids. The Δ8 unsaturatedsteroid 24,25-dihydrolanosterol acetate underwent allylic oxidation under these conditions.
