Direct C-H functionalization of aromatic compounds is a powerful tool for organic synthesis; however, differentiation amongst the ubiquitous and often chemically similar C-H bonds remains a significant challenge. Conflation with coordinating or directing groups incorporated into the intended substrate has helped address these limitations, although access to remote sites remains limited. Herein, we
芳香族化合物的直接 CH 官能化是有机合成的有力工具;然而,在普遍存在且通常化学上相似的 CH 键之间进行区分仍然是一个重大挑战。尽管对远程站点的访问仍然有限,但与合并到预期基板中的协调或指导组的合并有助于解决这些限制。在此,我们报告了一种操作简单且可持续的直接间位选择性 H2N 胺化,在足够温和的条件下对苄基和相关芳香族吡啶甲酸酯进行修饰,以修饰多功能和后期分子。
