mostly up to the γ‐position. In the present work, we demonstrate the diverse (hetero)arylation of amino acids and analogous aliphatic amines selectively at the remote δ‐position by tuning the reactivity controlled by ligands. An organopalladium δ‐C(sp3)−H activated intermediate has been isolated and crystallographically characterized. Mechanistic investigations carried out experimentally in conjunction
定向C H功能化已实现为传统方法的补充工具,可直接访问非蛋白原性
氨基酸。尽管这样的过程主要限于γ位置。在当前的工作中,我们通过调节
配体控制的反应性,证明了在远端δ位选择性地使
氨基酸和类似的脂肪族胺具有多种(杂)芳基化作用。已分离出
有机钯δ-C(sp 3)-H活化中间体,并进行了晶体学表征。实验研究与计算研究相结合进行的机理研究揭示了取决于基材结构的机理图上的差异。
