Abstract
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.
Keywords: Diimide reduction; Stereochemistry; Catalytic hydrogenation.
