An efficient method was developed to construct 2-pyridinones by the cycloaddition of nitro ketene aminal with 3-hydroxy-2-aryl-acrylate. The method uses readily-available starting materials and provided diverse bicyclic 2-pyridinones and multi-substituted 6-amino-2-pyridinones in good to excellent yields.
