Abstract
Catalytic epoxidation by dioxygen of (Z)-17-ethylideneandrostane in th e presence of dioxoruthenium(vl) tetramesitylporphyrinate affords as m ajor products the two 17,20-epoxides in a non-stereoselective process; the occurrence of a minor competitive pathway leading to isomeric ole fins suggests the existence of a ruthenium(II) porphyrin intermediate.
