A relay catalysis strategy enables a [3 + 1]-annulation reaction between cyclopropane 1,1-diester and aromatic amines via lewis acid-catalyzed nucleophilic ring opening of cyclopropane 1,1-diester with aromatic amine and (hypo)iodite-catalyzed C-N bond formation. This reaction provides biologically important azetidines and tetrahydroquinolines.
