Aspects of stereochemistry. Part XXII. Epoxidation and hydrogenation of 4-methyl-3-oxo-Δ4-steroids
Abstract
Compared with the corresponding reactions of 3-oxo-Δ4-steroids, hydrogenation and alkaline epoxidation of 4-methylcholestenone and 4-methyltestosterone give higher proportions of 5α-products. α-Epoxides were obtained from reactions of cholestenone and 4-methylcholestenone with peroxylauric acid.
