Synthesis of 3-O-(beta-D-xylopyranosyl-(1-->2)-beta-D-glucopyranosyl)-3'-O-(beta-D-glucopyranosyl)tamarixetin, the putative structure of aescuflavoside A from the seeds of Aesculus chinensis.
3-O-(beta-D-xylopyranosyl-(1-->2)-beta-D-glucopyranosyl)-3'-O-(beta-D-glucopyranosyl)tamarixetin, the putative flavonal glycoside named aescuflavoside A, isolated from the seeds of Aesculus chinensis, is synthesized via regioselective glycosylation of 7-O-benzyltamarixetin with glycosyl bromides under phase-transfer-catalyzed conditions.
