A metal catalyst free approach for regioselective ortho-chlorination of anilines has been developed using a secondary amine as the organocatalyst and sulfuryl chloride as the halogen source under mild conditions. A wide range of substrates were compatible with this catalytic system. In addition, this catalytic protocol has been applied to the efficient synthesis of bioactive compounds and modification
使用仲胺作为有机催化剂和硫酰氯作为卤素源,在温和条件下开发了一种用于苯胺区域选择性邻氯化的无金属催化剂方法。多种底物与该催化系统相容。此外,该催化方案已应用于生物活性化合物的高效合成和药物衍生物的修饰。进一步的研究表明阴离子三氯化物是邻位选择性的原因。
