A robust method for the synthesis of benzo[c]isothiazole 2‐oxides has been developed providing a range of functionalized derivatives starting from anilines and DMSO. The reaction sequence can be performed on a gram scale and leads to products that can easily be modified by standard cross‐coupling reactions.
已开发出一种可靠的合成苯并[ c ]异噻唑2-氧化物的方法,可提供从苯胺和DMSO开始的一系列功能化衍生物。反应顺序可以以克为单位进行,可以生成可以通过标准交叉偶联反应轻松修饰的产物。
