antiarthritis activity. Further biological studies have been limited because of the limited availability of 1 from natural sources. Herein the first total synthesis of 1 in an overall yield of 8.3% is described. The synthesis involved the regio- and stereoselective glycosylation–Fries-type O-to-C rearrangement to construct the C-aryl glycosidic linkage, followed by a Baker–Venkataraman rearrangement and cyclodehydration
