An efficient three-component domino or one-pot strategy has been developed for the synthesis of medicinally important benzothiophene and benzothiopheno[2,3-e]azepinedione derivatives for the first time. Amine-promoted selective cleavage of C–S bond of thioisatin is the key step in this process. The reported methodology benefits from environmentally friendly solvent (H2O), wide substrate scope, good
首次开发了一种有效的三组分多米诺骨牌或一锅法,用于合成具有医学重要性的苯并噻吩和苯并噻吩[2,3- e ]氮杂二酮衍生物。胺促进的硫代丝氨酸的C–S键选择性裂解是该过程的关键步骤。报告的方法得益于环保溶剂(H 2 O),较宽的底物范围,良好的官能团耐受性和较高的反应产率。
