Synthesis of tamarixetin and isorhamnetin 3-O-neohesperidoside
摘要:
Two isomeric flavonol 3-O-glycosides, tamarixetin and isorhamnetin 3-O-neohesperido side (1 and 2), were synthesized. The natural product from Costus spicatus assigned as the former compound is revised to the latter structure. (c) 2005 Elsevier Ltd. All rights reserved.

Synthesis of 3-O-(β-d-xylopyranosyl-(1→2)-β-d-glucopyranosyl)-3′-O-(β-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 flavorial glycoside named aesculflavoside 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.
