探索一种潜在的催化剂系统,以实现催化剂控制的C-S键形成选择性是一项迷人的挑战。在此,我们描述了两种新的和高效的方法选择性合成C2-和C3-磺酰基吲哚显示良好的生物活性,分别使用碘化物和铜催化剂。机理研究指出磺酰化中间体的电子性质的关键作用。
Exploring a potential catalyst system for catalyst‐controlled selectivity in C−S bond formation is a fascinating challenge. Herein, we described two novel and highly efficient methods for the selective synthesis of C2‐ and C3‐sulfonylindoles showing good biological activities by employing iodide and copper catalysts, respectively. Mechanistic studies point to the crucial role of the electronic properties of the sulfonylated intermediates.
