yields with high regioselectivity from readily available aromatic compounds and aryl/alkyl thiols, even on gram scale. To demonstrate the practicability of this reaction, two bioactive compound skeletons were synthesized in good yields. This method can also be used to late‐stage modification of curcumin.
在空气中已经开发出一种简单实用的NaI催化的芳烃直接CH磺酰化方法。在该反应中,即使是按克规模,也从容易获得的芳族化合物和芳基/烷基硫醇以中等至优异的产率和高的区域选择性获得芳基硫化物。为了证明该反应的实用性,以高收率合成了两个生物活性化合物骨架。此方法也可用于姜黄素的后期修饰。
