yielded a mixture of two diastereomeric diols, the 16α-hydroxymethyl,17β-hydroxy and 16β-hydroxymethyl,17α-hydroxy isomers (17a-20a) in a ratio of 6:1. We describe a straightforward synthetic route to transform the isomers with trans functional groups attached to ring D (17a-20a) into isomers with cis functional groups (25a-28a). We determined the in vitro antiproliferative activities of compounds 17a-20a
