less reactive aryl bromides as arylating reagents in the Pd(II)-catalyzed intermolecular arylation of unactivated C(sp3)–Hbonds is described. This reaction was promoted by a crucial 8-aminoquinolinyl directing group and a K2CO3 base, enabling regiospecific installation of an aryl scaffold at the β-position of carboxamides.

描述了在Pd(II)催化的未活化C(sp 3)-H键的分子间芳基化中使用容易获得的,反应性较低的芳基溴化物作为芳基化试剂的示例。至关重要的8-氨基喹啉基导向基团和K 2 CO 3碱促进了该反应,从而使芳基骨架可以在羧酰胺的β-位上进行区域特异性安装。通过DFT计算进行的机理研究揭示了C(sp 3)–H活化为主导的途径,该途径的特征是氧化加成为最高能量跃迁状态。

Synthesis of Alkyl-Substituted Pyridines by Directed Pd(II)-Catalyzed C–H Activation of Alkanoic Amides
作者:Thorsten Bach、Peng Hu
DOI:10.1055/s-0035-1560810
日期:——
A general alkylation protocol for substituted iodopyridines was developed (32 examples, 44-97% yield). The reaction is based on the Pd(II)-catalyzed C-H activation of 8-aminoquinoline-derived alkanoic amides and it employs a catalyst cocktail of Pd(OAc)(2) (10 mol%), NaI (30 mol%), and (BuO)(2)POOH (20 mol%), with Ag2CO3 as base.
