Abstract

The manuscript describes an investigation on the reaction pathways followed in the reactions of variedly substituted thioamides and the corresponding 1,3-diazabuta-1,3-dienes with dimethyl acetylene dicarboxylate. The mechanistic rationales for the reactions pathways followed have been plausibly explicated. The study assumes considerable significance because of the formation of novel functionalized heterocycles.
