Facile synthesis of coumaronochromones through palladium-catalyzed intramolecular cross dehydrogenative coupling

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%).

Synthesis of Demethoxycapillarisin, a Naturally Occurring 2-Phenoxychromone, and Related Compounds

Demethoxycapillarisin (1), a naturally occurring 2-phenoxychromone, and the related compounds (2) - (4) have been synthesized via a route involving, as a key step, an intramolecular Wittig reaction between a phosphorus ylide and a carbonate.
