Palladium-catalyzed oxidative [4+2] cyclization reactions were developed from the C?H activation reaction of N-methoxyazulene-1- and 2-carboxamides with symmetrical and unsymmetrical alkynes under a molecular oxygen atmosphere, producing azulenopyridinone derivatives with novel azulene skeletons in good to excellent yields with a wide substrate scope and excellent functional group tolerance.
