A one-pot, two-stage synthesis of diaryl sulfonamides using sequential iron and copper catalysis is developed. Regioselective para-iodination of activated arenes by the super Lewis acid, iron triflimide and N-iodosuccinimide (NIS), is followed by a copper(I)-catalyzed N-arylation reaction. The process is found to be applicable for the coupling of a range of anisoles, anilines and acetanilides with
开发了使用顺序铁和铜催化的二芳基磺酰胺的一锅两步合成。通过超级路易斯酸、三氟酰亚胺铁和N-碘代琥珀酰亚胺 (NIS) 对活化的芳烃进行区域选择性对位碘化,然后进行铜 (I) 催化的N-芳基化反应。发现该方法适用于一系列苯甲醚、苯胺和乙酰苯胺与伯磺酰胺的偶联,并用于一锅法合成生物学上重要的化合物。
