Heterocyclic synthesis with activated nitriles : An expeditious synthetic approach to polyfunctionally substituted pyrroles, heterocyclopyrimidines and coumarins

Abstract

The applicability and synthetic potency of the new reagent N-(2,2-dicyanoethenyl)aminoacetonitrile (3) to develop an expeditious convenient synthetic route of unique polyfunctionally substituted pyrroles, heterocyclopyrimidines and 2H-1-benzopyran-2-ones is reported. Chemical and spectroscopic evidence for the structures of the newly synthesized compounds are described.
