The present invention relates to methods of synthesising aziridines including isotopically labelled aziridines, said methods comprising contacting an imine or one or more precursors thereof with a diazo compound in the presence of a phosphoramide or a phosphoramide-derived catalyst. The present invention also relates to aziridines, modified aziridines and aziridine-derived compounds preparable by the aforementioned methods, and to phosphoramide or phosphoramide-derived catalysts suitable for use in such methods.
Despite the remarkable advances in catalytic asymmetricaziridinations over the past decades, establishing a general procedure for the stereoselective synthesis of trisubstituted aziridines has remained an elusive goal. Chiral N-triflyl phosphoramide-catalyzed reactions of N-α-diazoacyl oxazolidinones and N-Boc imines were developed as a solution to this unmet challenge.
