Two isomeric dimeric steroids, 3, 3′-bis (methyl 3-hydroxyandrost-4-en-17-on-19-oate-3- yl), with symmetrical (α, α′) and unsymmetrical structures (α, β′), have been obtained by reduction of methyl androst-4-ene-3, 17-dion-19-oate with zinc in aqueous acetic acid together with the major products, the isomeric methyl 5α-and 5β-androst-3-en-17-on-19- oates. The structures of the dimers and unsaturated products are supported by ...
