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.
从七叶树种子中分离得到的假定黄酮苷3 - O -（β - D - 吡喃木糖基 -（1→2）-β - D - 吡喃葡萄糖基）- 3'- O -（β - D - 吡喃葡萄糖基）柽柳素，即七叶黄酮苷A，是在相转移催化条件下，通过7 - O - 苄基柽柳素与糖基溴进行区域选择性糖基化反应合成的。
