Abstract

A divergent protocol for the selective synthesis of benzofuran-2-carboxaldehydes and 3-organoselenyl-2H-coumarins from propargylic aryl ethers in the presence of dialkyl(aryl) diselenides under electrochemical reaction conditions was established. By adjusting the reactant ratio, reaction time and temperature, two significant heterocyclic derivatives could be selectively obtained with high yields, respectively. The reaction was performed under simple reaction conditions and was suitable for various substituted propargylic aryl ethers and dialkyl(aryl) diselenides.

通过电化学串联环化反应从芳基丙炔醚中选择性地合成苯并呋喃和香豆素

在电化学反应条件下，在二烷基（芳基）二硒化物存在下，建立了从丙炔基芳基醚选择性合成苯并呋喃-2-甲醛和 3-有机硒基-2H-香豆素的不同方案。通过调节反应物比例、反应时间和温度，可分别选择性地获得两种重要的杂环衍生物，且产率较高。该反应在简单的反应条件下进行，适用于各种取代的丙炔基芳基醚和二烷基（芳基）二硒化物。
