“…By circumventing the pregeneration of sensitive organometallics, transition-metal-catalyzed cross-electrophile ring opening (XERO) of cyclic compounds represents an appealing reaction toward C–C bond formation from the viewpoints of step-economy, functional group compatibility, and operational simplicity. , To date, suitable heterocyclic precursors for XERO mainly include epoxides, aziridines, cyclic anhydrides, benzofurans, and heteroatom-bridged bicyclic alkenes . Among them, aziridines are versatile building blocks in organic synthesis, and XERO of such a structural motif with aryl iodides, alkenyl bromides, aldehydes, acetals, CO 2 , or Michael acceptors provides approaches to a variety of amine derivatives (Scheme A).…”
