Abstract

A simple method has been developed for one-pot synthesis of five-, six- and seven-membered cyclic N-sulfonylamidines from lactams and sulfonamides under mild conditions. The method involves a Vilsmeier like reaction promoted by phosphoryl chloride. Detailed synthetic studies showed that the corresponding substituted N-sulfonylamidines were obtained in moderate to good yields.
