Shi epoxidation

From Wikipedia, the free encyclopedia

The Shi epoxidation is a chemical reaction described as an asymmetric epoxidation of olefins with oxone and a fructose-derived catalyst (1).[1][2]

The Shi epoxidation

This procedure generates epoxides with high enantiomeric excesses from trans-disubstituted alkenes and trisubstituted alkenes. Cis-disubstituted alkenes[3] and styrenes[4] are asymmetrically epoxidized using a similar catalyst.
