A series of 3‐cyano‐2‐pyridone derivatives were synthesized by one‐pot four‐component condensationreaction involving a benzaldehyde derivative, alkyl cyanoacetate, acyclic or cyclicketones, and ammonium acetate in reflux condition. The X‐ray structure of the products 5a and 5d confirm symmetric dimers via hydrogen bonding interactions between individual pyridine molecules showing, in addition, also
