Abstract

The Diels-Alder cycloaddition of nitroethylene to some androsta-14,16-dien-17-yl acetates has been studied. The addition occurs stereoselectively, giving predominantly head-to-head-adduct. 14β-Cyanomethyl steroids were obtained via the reductive cleavage reaction of bridged nitro compounds. The structures of the new compounds have been fully characterized by 2D NMR and tandem mass-spectrometry methods.
