Reaction Conditions

Reaction Steps

A solution of 23.3 g of 3β-acetoxy-17,17-ethylenedioxy-15β,16β-methylene-5-androsten-7β-ol in 350 ml of toluene was combined dropwise, after adding vanadium(IV) oxide acetylacetonate, within 35 minutes with 23.3 ml of 80% tert.-butyl hydroperoxide, dissolved in 115 ml of toluene. The reaction solution was maintained at 80° C. for another 30 minutes, then cooled, diluted with diethyl ether, washed with sodium bisulfite solution, sodium bicarbonate solution, and water, and dried and evaporated, thus obtaining 24.5 g of 3β-acetoxy-5,6β-epoxy-17,17-ethylenedioxy-15β,16β-methylene-5β-androstan-7β-ol, mp 162°-163° C. (diisopropyl ether).
