Abstract

Enantioselective epoxidations of alkenes were achieved using a Shi-type carbohydrate-derived hydrate and Oxone. The chiral platform provided by the catalyst tolerates a wide range of substituents providing high yields and enantioselectivities. However, styrene derivatives were only converted with poor selectivities.
