โœฆ Synopsis


The response of the asymmetric epoxidation reaction to steric bulk in the substrate is tested by use of allylic alcohols with tert-butyl groups at each one of four possible positions.

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
