Abstract

An efficient palladium-catalyzed cross-coupling reaction of 4-hydroxy-pyrone or 4-hydroxy-2 (5H)-furanone with arylboronic acid is described, which affords the 4-substituted-pyrones and 2 (5H)-furanones in good yields. This transformation proceeds through a C–OH bond activation under mild conditions.
