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.

The invention relates to the field of chemical synthesis, and specifically disclose a preparation method of 1,6,7-trihydroxy-3-methoxyl xanthone-2-C-beta-D-glucopyranoside. According to the method, mangiferin is adopted as a raw material, and 3-methoxyl mangiferin is prepared through boric acid esterification, selective methylation, and hydrolysis reactions. The method provided by the invention has the advantages of short synthesis route, high product yield, low-toxic safe reagent, low production cost, and suitability for large-scale industrial productions.

supporting information; experimental part, p. 5725 - 5728 (2010/10/03)
Mangiferin, isomangiferin, and homomangiferin, the xanthone C-glycosides with a wide spectrum of pharmacological effects, were synthesized concisely, featuring a C-glycosylation of a xanthene derivative with perbenzylglucopyranosyl N-phenyltrifluoroacetimidate.
