Trans hydrindanes by dimide reduction: Synthesis of dihydro-B-nortestosterone and its 17α-methyl derivative

Reductive hydroboration of Δ5-B-norsteroids (e.g., 1) affords 5α-dihydro products (e.g., 3) in a low yield. Better yields, were obtained by reduction with diimide. The method was employed in the synthesis of potential antiandrogens - 17β-hydroxy-B-nor-5α-androstan-3-one (8) and its 17α-methyl derivative (9).

Reduction with diimide was employed in the synthesis of potential antiandrogens - 17β-hydroxy-B-nor-5α-androstan-3-one (26) and its 17α-methyl derivative (25). Other methods of reduction (hydroboration, catalytic hydrogenation) were less effective.
