Abstract

11β-Hydroxyandrost-4-ene-3,17-dione (III) was converted into a potential metabolite of epitestosterone - 11β,17α-dihydroxyandrost-4-en-3-one (II) in 5 steps, including the inversion of configuration of a 17β-hydroxy group. This inversion was not feasible in the preparation of the analogues X, XIV, XX, and XXII, where the 17α-hydroxy group was introduced first and only then was the rest of the molecule modified.
