Copper efficiently catalyzes a reaction of N-sulfonylaziridines and N-alkylanilines in the presence of tert-butyl hydroperoxide to afford functionalized imidazolidines via nucleophilic ring opening, sp3 C-H functionalization, and C-N bond formation. The protocol can be used for the enantiospecific synthesis of imidazolidines with excellent optical purity.
