Total synthesis of mangiferin, homomangiferin, and neomangiferin, three C-glycosyl xanthone natural products with a wide spectrum of pharmacological effects, has been achieved starting from 2,3,4,6-tetra-O-benzyl-α/β-d-glucopyranose. The key steps involve a stereoselective Lewis acid promoted C-glycosylation of protected phloroglucinol with tetrabenzylglucopyranosyl acetate and a highly regioselective base-induced cyclization for the construction of the core xanthone skeleton.

C-Glucosylation of oxysubstituted benzene derivatives with O-α-D-glucopyranosyl trichloroacetimidate gave mainly β-D-glucopyranosylarenes.The most efficient catalysts were diethyl ether*boron trifluoride, diethyl ether*zinc chloride and zinc chloride.The
