Abstract

In the preceding paper in this issue 1 we showed that 2-chloro-1,3-dimethylimidazolinium chloride (DMC) (1) was a good dehydrating agent and that 1 could be superior to dicyclohexylcarbodiimide (DCC) (2) (Chart 1). In this paper we describe the additional capability of 1 to construct heterocycles based on dehydration reactions. ... Sydnone Synthesis. It is well-known that sydnones are easily synthesized by the cyclodehydration of N-substituted N-nitroso-α-amino acids. 2 Thus, we ...
