The reaction between N-chloro-N'-benzenesulfonylbenzamidines and ß,ß-disubstituted enamines affords N-(benzenesulfonyl)-N'- [(2-chloro-2-substituted-l-amino)-propyl]-benzamidines.

Abstract
The reaction between N-chloro-N'-benzenesulfonylbenzamidines and ß,ß-disubstituted enamines affords N-(benzenesulfonyl)-N'- [(2-chloro-2-substituted-l-amino)-propyl]-benzamidines. When both ß-substi tuents 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.Pubblicazioni consigliate
