A copper(II)-catalyzed reaction of -azido-N-allylamide synthetic under an oxygen atmosphere resulted in the formation of 2-formyl pyrazinones. The present transformation was characterized by the following steps: 1) 1,3-dipolar cycloaddition of the azido part onto the intramolecular alkene to give bicyclic aziridine intermediates; 2) further copper(II)-catalyzed oxygenation-oxidation of the aziridines to give 2-formyl pyrazinones.
