efficient synthesis of biologically active (E)-2-cyanoacrylamides and 3-substituted azetidine-2,4-diones has been reported with 64–94% yields under metal-free conditions. The reaction proceeds through sequential Knoevenagel condensation/stereoselective in situ monohydration of nitrile or C–N cyclization protocol in one-pot. The attractive features of this tandem process are moderate reaction conditions

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.
