Facile synthesis of 2,3-dihydrobenzofuran-3-ylacetic acids and related analogues was successfully carried out by a novel electrochemical aryl radical generation and its 5-exo cyclization followed by a carboxylation sequence of 2-allyloxybromobenzenes by using methyl 4-tert-butylbenzoate as an electron-transfer mediator.
以 4-叔丁基苯甲酸甲酯为电子转移介质,通过新型电化学芳基自由基生成及其 5-外向环化,然后通过 2-烯丙氧基溴苯的羧化序列,成功地合成了 2,3-二氢苯并呋喃-3-基乙酸及相关类似物。
