17-O-Acetyl testosterone, which has no susceptible hydroxyl or carboxyl group for glycosylation, was glycosylated with 2,3,4,6-tetra-O-acetyl-alpha-D-glucopyranosyl bromide in the presence of a mixed catalyst, Hg(CN)2 and HgBr2, in benzene-nitromethane. Reaction occurred on the alpha, beta-unsaturated ketone on the six-membered A-ring
