In this study, the convenient preparation of N2-unprotected five-membered cyclic guanidines was achieved via a cascade [3 + 2] cycloaddition between organo-cyanamides and alpha-haloamides under mild conditions in good to excellent yields (up to 99%). The resulting cyclic guanidines could be easily transformed into hydantoins through hydrolysis.
