Abstract Intramolecular copper-catalyzed aziridination of sulfamates occurs in very good yields of up to 86% and in up to 84% ee in the presence of (4S, 4′ S)-2, 2′-(propane-2, 2- diyl) bis (4-tert-butyl-4, 5-dihydro-1, 3-oxazole). The resulting aziridines undergo smooth ring opening with different types of nucleophiles in an SN 2-type process.
