Asymmetric Epoxidation of Electron-Deficient Olefins

This paper focuses on the latest developments in asymmetric epoxidation of electron-deficient olefins since the review by Por- ter and Skidmore on chiral ligand-metal peroxide systems, polyamino acid catalysed and organocatalysed epoxidations. Particular atten- tion has been paid to the most recent advances using chiral pyrrolidines as organocatalysts.
