Since the asymmetric epoxidation of allylic alcohols, which was reported by the Sharpless group in 1980, catalytic asymmetric epoxidation has been one of the most important asymmetric methodologies.[1] A number of methods have been developed for the epoxidation of both unfunctionalized olefins and electron-deficient enones.[2] Quite recently, catalytic asymmetric phase-transfer epoxidations by using a cinchona alkaloid-derived ...
