The stereochemistry of 3beta,17beta-dihydroxy-3alpha-ethylandrost-4-ene, 3alpha,17beta-dihydroxy-3beta-methylestr-4-ene and 3beta-acetoxy-7alpha,17beta-dihydroxy-7beta-methylandrost-5-ene, which were obtained by Grignard reactions from the corresponding alphabeta-unsaturated ketones, have been established by X-ray crystallography.
