Nitriles in Heterocyclic Synthesis: New Route fot the Synthesis of Pyridine and Pyrido[2,3-d]pyridazine Derivatives

Abstract

Several new 2-cyanohydrazonomethyl pyridines and pyrido[2,3-dlpyridazine derivatives were obtained via the reaction of arylhydrazononitriles with 2-amino-1,1,3+ricyanopropeneand diethyl 3-amino-2-cyanopent-2-ene-dicarboxylate.1 3 .
