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.

We present an efficient and facile synthesis of 4,6-diaryl-2-oxo-1,2-dihydropyridine-3-carbonitriles (5a–j) via a four-component system of aromatic aldehydes (1), acetophenones (2), ethyl cyanoacetate (3), and ammonium acetate (4). The short reaction time coupled with the simplicity of the reaction procedure and clean reaction make this method one of the most efficient methods for synthesis of this class of compounds.
