Microwave assisted non-catalytic condensation of 2-cyanoacetamide with aromatic aldehydes, and enolate mediated Michael-type addition to acrylamide followed by oxidative cyclization, produce 2-pyridones in good to excellent yield. Unsymmetrical ketones produce two regioisomeric enolates, therefore thermodynamic and kinetic products of butan-2-one and pentan-2-one have been isolated and fully characterized. This journal is

A series of 3-cyano-2-pyridone derivatives were synthesized by one-pot four-component condensation reaction involving a benzaldehyde derivative, alkyl cyanoacetate, acyclic or cyclic ketones, 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 π-π stacking interactions.
