3-Amino-5-cyanomethylpyrazole-4-carbonitrile: Versatile Reagent for Novel Bis(pyrazolo[1,5-a]pyridine) Derivatives via a Multicomponent Reaction

摘要

An efficient synthesis of novel bis(pyrazolo[1,5-a]pyridine) derivatives through Michael addition reaction of 3-amino-5-cyanomethylpyrazole-4-carbonitrile with bis-arylidenemalononitrile is reported. All new compounds are characterized by different spectral tools.
