A two-pot synthesis of thieno[3,2-b]indole from 2,5-dibromothiophene is described. A halogen dance of 2,5-dibromothiophene was performed with LDA, and subsequent Negishi coupling was performed with 2-iodoaniline derivatives to provide the corresponding coupling products. The resulting two bromo groups have different reactivities, which were utilized for the one-pot Suzuki–Miyaura coupling/intramolecular
描述了由2,5-二溴噻吩两联合成噻吩并[3,2- b ]吲哚。用LDA进行2,5-二溴噻吩的卤素舞,随后用2-碘苯胺衍生物进行Negishi偶联,以提供相应的偶联产物。所得的两个溴基团具有不同的反应性,可用于一锅Suzuki-Miyaura偶联/分子内Buchwald-Hartwig胺化反应,并通过参与原位配体交换的辅助串联催化生成噻吩并[3,2- b ]吲哚。
