Vorschrift

Substituting 4,7α-dimethyl-4-androstene-3β,17β,19-triol, 7α,17α-dimethyl-4-androstene-3β,17β,19-triol and 7α-methyl-17α-propinyl-4-androstene-3β,17β,19-triol for the 7α-methyl-4-androstene-3β,17β,19-triol above results in the formation of 17β,19-dihydroxy-4,7α-dimethyl-4-androsten-3-one, 17β,19-dihydroxy-7α,17α-dimethyl-4-androsten-3-one and 17β,19-dihydroxy-7α-methyl-17α-propinyl-4-androsten-3-one, respectively.
