Abstract An efficient and facile synthesis of 4,6‐diaryl‐2‐oxo‐1,2‐dihydropyridine‐3‐carbonitriles via three‐component cyclocondensation from aromatic aldehydes, aromatic ketones, and 2‐cyanoacetamide under solvent‐freeconditions is described. The mild reaction conditions, simple protocol, and clean reaction make this protocol practical and economically attractive.
