An efficient synthesis of 2,3-aziridino-γ-lactones from azetidin-2-ones

An efficient synthesis of enantiopure 2,3-aziridino-γ-lactones from azetidin-2-ones is described. Acid-catalyzed tandem intramolecular azetidinone ring opening followed by aziridine ring formation via elimination of a mesylate group is the key step in thi
