The total synthesis of coriariin B (1), which is a type of ellagitannin, and originally obtained from the leaves of Coriaria japonica, was achieved by esterification between the glucose derivative and partially protected dehydrodigallic acid (5). The HHDP (hexahydroxydiphenoyl) unit was constructed by the oxidative phenol coupling reaction in a stereoselective manner.
