Synthesis of quercetin 3-O-β-d-apiofuranosyl-(1→2)-[α-l- rhamnopyranosyl-(1→6)]-β-d-glucopyranoside

Zhang, Yang,Wang, Kejun,Zhan, Zhilai,Yang, Yu,Zhao, Yimin

, p. 3154 - 3157 (2011/06/28)

A concise method to construct a unique 2,6-branched trisaccharide was established by regioselective glycosylation of three free hydroxyl groups on a 3-O-protected glucose moiety, and successfully used in the synthesis of quercetin 3-O-β-d-apiofuranosyl-(1→2)-[α-l-rhamnopyranosyl- (1→6)]-β-d-glucopyranoside, a flavonol O-glycoside isolated from glandless cotton seeds which showed notable antidepressant activities.
