Abstract
3β-Hydroxy-androst-5-en-16-one (Va) was synthesized selectivelyth by e demesyloxylation and hydrolysis with alkali from 17ξ-mesyloxy-3β, 16β-diacetoxy-androst-5-ene (IV), which was derived from dehydroepiandrosterone (I) with fourstep sequences : enol acetylation, oxidation with lead tetraacetate, reduction, and mesylation.Keywords
