The reaction between N-chloro-N'-benzenesulfonylbenzamidines and β,β-disubstituted enamines affords N-(benzenesulfonyl)-N'-<(2-chloro-2-substituted-1-amino)-propyl>-benzamidines.When both β-substituents are methyl groups the open chain adducts have been isolated and characterized, whereas, when one of the two substituents is a phenyl group, they have been characterized only by PMR because of the easy cyclization to 1-benzenesulfonyl-4,5-dihydroimidazoles.
