The greater yield (61%) of the 6-ketone (2a) from 3a-acetoxy-5,6a-epoxy-5a-cholestane (la) compared with the yield (34%) of B-ketone (2b) from the corresponding 3-deoxy compound has been ascribed' to the energetically favourable conformational change, involving the 3-acetoxy group, in the formation
