Steroidal 6-nitroolefins (I-IV) undergo facile reaction with NH3-MeOH-Zn yielding exclusively the corresponding 6-one oximes (V-VIII) in quantitative yields.The method appears to be of general applicability.

4α,5α, 4β,5β- and 5β, 6β-Epoxycholestanes give backbone rearranged compounds on BF3-catalysed rearrangement. Solvent changes markedly affect the products of rearrangement. 4α-Hydroxycompounds arise from the 4β,5β-epoxide on BF3-catal
