来源于Quintinia 树叶中提取2,3,2",3"-Tetrahydroochnaflavone的天然双黄酮首次被全合成. 该化合物包含naringenin和eriodictyol分子单元, 以4-羟基苯甲醛和2,4,6-三羟基苯乙酮为原料, 关键步骤是通过Ullmann反应形成二芳醚单元和对醚键连接的双查尔酮进行环化得到目标产物. 新化合物的结构经过1H NMR, 13C NMR和HRMS确认.

The first total synthesis of (±)-2,3,2",3"-tetrahydroochnaflavone has been achieved, which was isolated from the leaf of quintinia. The target molecular is consisting of naringenin and eriodictyol moieties, which was synthesized using 2,4,6-trihydroxyacetophenone and 4-hydroxybenzaldehyde as starting materials. The key steps in the synthesis of 2,3,2",3"-tetrahydroochnaflavone were the formation of a diaryl ether and cyclization of an ether-linked bichalcone to assemble the dihydroflavone, and the key synthetic intermediates are detailed.

Key words: (±, )-2,3,2",3"-tetrahydroochnaflavone, bioflavonoids, Ullmann reaction, total synthesis
