A CHactivation strategy has been successfully employed for the high‐yielding synthesis of a diverse array of 4‐substituted2‐quinolinone species by a palladium‐catalyzed dehydrogenative coupling involving diarylamines. This intermolecular annulation approach incorporates readily available α,β‐unsaturated carboxylic acids as the couplingpartner by suppressing the facile decarboxylation. Based on
AC ħ激活策略已被成功地用于通过涉及二芳基胺钯催化脱氢偶联高产合成4-取代的2-喹啉酮物种的多样性阵列的。这种分子间环化方法通过抑制容易的脱羧作用,结合了易于获得的α,β-不饱和羧酸作为偶联伴侣。在初步的机理研究的基础上,提出了一个反应顺序,包括邻,π-配位,β-迁移插入和β-氢化物消除。
