Nitriles in Heterocyclic Synthesis: New Approaches for Synthesis of Some Pyridine Derivatives

Abstract A variety of pyridines was prepared from reaction of N-benzylidenecyanoethanoic hydrazide (2) with malononitrile, benzoylacetonitrile, cyanoacetamide and cinnamonitrile derivatives. The reactivity of 2 towards a variety of ketones was studied.
