An AcOH-mediated three-component reaction of 2-aminothiophenols, α,β-unsaturated aldehydes, and thiophenols to prepare the high value-added 2-thioalkylbenzothiazoles was developed. The reaction was conducted under metal-free conditions, where oxygen served as the terminal oxidant. In addition, this strategy is tolerant of kinds of functional groups, providing efficient access to a variety of functionalized
开发了AcOH介导的2-氨基硫酚,α,β-不饱和醛和硫酚的三组分反应,以制备高附加值的2-硫代烷基苯并噻唑。该反应在无金属的条件下进行,其中氧气用作末端氧化剂。另外,该策略可耐受各种官能团,从而以中等至良好的产率有效地获得各种官能化的苯并噻唑衍生物。而且,该反应具有完全的区域反射性,为构建复杂分子提供了有力的方法。
