In a direct route for the synthesis of alkyl-substituted chiral aziridines from achiral starting materials, readily accessed allylic hydroxylamine esters undergo copper hydride-catalyzed intramolecular hydroamination with a high degree of regio- and enantiocontrol to afford the aziridine products in good to excellent yields in highly enantioenriched form.
