三聚联苯醚类大环化合物的合成

Synthesis of Macrocyclic Biphenol Trimers

在温和条件下,以3,3'-二溴-4,4’-联苯二酚和1,2-二溴乙烷或1,4-二溴丁烷为原料,经过两步反应方便地合成了三聚联苯醚类大环化合物4a和4b,并通过1H NMR,13C NMR,HRMS对中间体和目标化合物的结构进行了表征。

Two annulated biphenol trimers 4a and 4b were synthesized via two steps using 3,3＇-dibromo- 4,4＇-biphenol and 1,2-dibromoethane or 1,4-dibromobutane as starting materials. The structures of intermediates and products were determined by ^1H NMR, ^13C NMR and HRMS techniques.
