Abstract

Abstract: An efficient base-free palladium-catalyzed intramolecular cross dehydrogenative coupling of 2-aryloxy substituted 4-chromenones to access coumaronochromones has been achieved. A range of diversely substituted coumaronochromones can be facilely synthesized in good to excellent yields (up to 90%).
