Reaction Steps

Following essentially the same procedure but substituting 1α-methyl-4-androstene-17β,19-diol, 1α-methyl-4-androstene-3β,17β,19-triol and 7α-methyl-4-androstene-3β,17β,19-triol for the androst-4-ene-3β,17β,19-triol above results in the formation of 1α-methyl-17β,19-di(trimethylsiloxy)androst-4-ene, 1α-methyl-3β,17β,19-tri(trimethylsiloxy)androst-4-ene and 7α-methyl-3β,17β,19-tri(trimethylsiloxy)-4-androstene, respectively.
