Organocatalytic Enantioselective Desymmetrization of meso-Aziridines and Prochiral Azetidines

Catalytic enantioselective desymmetrization of meso-aziridines and azetidines is a powerful strategy for rapid synthesis of chiral building blocks. This review summarizes the progress in the development of these reactions by organocatalysis. Keywords: Organocatalysis, desymmetrization, aziridine, azetidine, strained ring.
