A convenient method for the synthesis of oxyresveratrol catalyzed by palladium is described. 2,4-Dihydroxyiodo-benzene underwent Heck reaction with acrylic acid, then decarboxylation, and further underwent Heck reaction with 3,5-dihydroxyiodobenzene, furnishing oxyresveratrol in a high yield. The title compound was characterized by MS and NMR. This synthetic method has several advantages such as less step processes, high yield, simple operations, and promises to be applied in industrial production.
