A mild, practical, metal and oxidant-free methodology for the synthesis of various C-3 selenylated benzo[b]furan derivatives was developed through the intramolecular cyclization of alkynes promoted with diselenides via electrooxidation. A wide range of selenium-substituted benzo[b]furan derivatives were obtained in good to excellent yields with high regioselectivity under constant current in an undivided
通过用二硒化物通过电氧化促进炔烃的分子内环化,开发了一种温和、实用、无金属和无氧化剂的方法,用于合成各种 C-3 硒化苯并[ b ]呋喃衍生物。在分别配备碳和铂板作为阳极和阴极的未分隔电池中,在恒定电流下以良好至优异的产率获得了范围广泛的硒取代的苯并[ b ]呋喃衍生物,具有高区域选择性。此外,收敛方法表现出良好的官能团耐受性,并且可以很容易地以良好的效率进行放大,从而从简单、容易获得的起始材料中快速获得各种硒化苯并[ b ]呋喃衍生物。
