Procedure

Substituting 1α,7α-dimethyl-17β,19-dihydroxy-5α-androstan-3-one, 4α,6α,17α-trimethyl-17β,19-di(2'-tetrahydropyranyloxy)-5α-androstan-3-one, 4α,17α-dimethyl-17β,19-di(4'-tetrahydropyranyloxy)-5α-androstan-3-one, 17β,19-dihydroxy-6α,17α-dimethyl-5α-androstan-3-one diacetate and 4α-methyl-17β,19-di(triphenylsiloxy)-5α-androstan-3-one for the 17β,19-dihydroxy-17α-methyl-5α-androstan-3-one above results in the preparation of 1α,7α-dimethyl-5α-androstan-17β,19-diol, 4α,6α,17α-trimethyl-17β,19-di(2'-tetrahydropyranyloxy)-5α-androstane, 4α,17α-dimethyl-17β,19-di(4'-tetrahydropyranyloxy)-5α-androstane, 6α,17α-dimethyl-5α-androstane-17β,19-diol diacetate and 4α-methyl-17β,19-di(triphenylsiloxy)-5α-androstane, respectively.
