ydrazide 2a, 2b, 2c were obtained via reaction of acetophenone derivatives 1a, 1b, 1c with cyanoacetic acid hydrazide. The hydrazidehydrazone derivative 2a underwent a novel series of heterocyclization reactions via its reaction with aromatic aldehydes and/or arylidenemalononitriles to produce arylidene and dihydropyridine derivatives 3 5l, respectively. Structures of the newly synthesized compounds
