Procedure
Substituting 1β,7α-dimethyl-5-androstene-3β,17β,19-triol 3,17-diacetate, 1β-methyl-5-androstene-3β,17β,19-triol triacetate and 1β,6-dimethyl-5-androstene-3β,17β,19-triol triacetate for the 1β-methyl-5-androstene-3β,17β,19-triol 3,17-diacetate above results in the preparation of 1β,7α-dimethyl-5α-androstane-3β,17β,19-triol 3,17-diacetate, 1β-methyl-5α-androstane-3β,17β,19-triol triacetate and 1β,6β-dimethyl-5α-androstane-3β,17β,19-triol triacetate, respectively.
