several hydroxylated steroids via conjugate addition of Fleming's silyl-cuprate reagent, (PhMe2Si)2CuLi, a masked hydroxyl group, to the appropriate enone was studied. By this means 7 alpha-hydroxytestosterone (7) was obtained in good yield from 17 beta-hydroxyandrosta-4,6-dien-3-one (1a), though similar reactions on 17 beta-hydroxyandrosta-1,4-dien-3-one (8) gave a low yield of 1 alpha-hydroxytestosterone
