실험 절차

Following essentially the same procedure and substituting 17β,19-dihydroxy-7α-methyl-4-androsten-3-one diacetate, 7α-methyl-17β,19-di-(2'-tetrahydropyranyloxy)-4-androsten-3-one and 19-hydroxy-1β-methyl-4-androsten-3,17-dione for the 17β,19-dihydroxy-4-androsten-3-one above results in the preparation of 7α-methyl-4-androstene-3α,17β,19-triol 17β,19-diacetate, 7α-methyl-17β,19-di-(2'-tetrahydropyranyloxy)-4-androsten-3α-ol and 1β-methyl-4-androstene-3α,17β,19-triol, respectively.
