Two series of chiral allylic alcohols, derived from c~,~-unsaturated cyanohydrins, were subjected to asymmetric epoxidation under a variety of conditions. Both achiral (organic peracid, metal-catalyzed peroxide) and chiral (Sharpless titanium-tartrate system) oxidants were applied. Several threo and
