Among heteroatom oxidations, the conversion of amines to N-oxides is a critical and challenging facet. Herein, the authors present an enantioselective N-oxidation methodology for both cyclic and acyclic amines, employing an ion-pair catalyst comprising a chiral bisguanidinium cation and an achiral oxodiperoxomolybdosulfate anion.
