sequential iron and copper catalysis. Regioselective ortho-activation of anisoles, anilines and phenols was achieved through iron(III) triflimide catalysed iodination, followed by a copper(I)-catalysed, ligand-assisted coupling reaction with N-heterocycle, amide and sulfonamide-based nucleophiles. The synthetic utility of this one-pot, two-step method for the direct amination of ortho-aryl C–H bonds was
使用连续的铁和铜催化作用,已经开发出一种用于将芳烃与非活性N-亲核试剂进行邻位偶联的一锅法。通过三氟化铁(III)催化的碘化作用,然后进行铜(I)催化,配体辅助的偶联反应,再与N杂环,酰胺和磺酰胺基亲核试剂实现对茴香醚,苯胺和苯酚的区域选择性邻位活化。一锅两步法直接合成邻位氨基甲酸酯的合成工具3,4-二氢喹啉-2-酮的后期官能化表明了芳基CH键。这允许制备TRIM24溴结构域抑制剂和一系列新的类似物。
