A hydrazide catalyst is introduced for the late-stage halogenation of peptides, drugs and (hetero)aromatics with high efficiency and selectivity. The active site comprises the hydrazide group attached to a sulfonamide moiety, which facilitates the acceptance as well as delivery of halonium species from the N-halosuccinimide source to the substrates, thus featuring a cooperative interaction.
引入酰肼催化剂,用于高效、选择性地对肽、药物和(杂)芳族化合物进行后期卤化。活性位点包含连接到磺酰胺部分的酰肼基团,这有利于卤鎓物质从N-卤代琥珀酰亚胺源到底物的接受和递送,从而具有协同相互作用的特征。
