regioselective carbon–sulfur-bond-forming electrophilic aromatic substitution reaction. The reaction occurred under mild conditions, and the products were obtained in good to excellent yields. The method represents an efficient preparation of sulfenyl aza-aromatics, which are useful intermediates for important organic transformations, due to the great importance of functionalized indoles among natural compounds
富含电子的氮杂芳族化合物如吲哚和吡咯是有机化学中特别感兴趣和重要的结构。描述了使用 S-烷基-和 S-芳基硫代邻苯二甲酰亚胺作为亚磺酰化剂将亚磺基区域选择性引入富电子氮杂芳烃的有用方法。CeCl3·7H2O/NaI 的催化量对于促进这种区域选择性碳-硫键形成亲电芳香取代反应至关重要。该反应在温和的条件下进行,以良好至极好的收率获得产物。由于功能化吲哚在天然化合物和药物产品中的重要性,该方法代表了硫基氮杂芳烃的有效制备,它们是重要有机转化的有用中间体。
