A palladium‐catalyzed [5+1] annulation of 2‐(1‐arylvinyl) anilines and α‐diazocarbonyl compounds has been developed, affording a series of multi‐functionalized quinolines in moderate to good yields. This procedure proceeded with the sequential insertion of N−H bond to the palladium carbene, intramolecular Heck reaction and decarboxylation steps. In this reaction, alkyl 2‐diazophenylacetates served
已经开发了钯催化的2-(1-芳基乙烯基)苯胺和α-重氮羰基化合物的[5 + 1]环化反应,可提供中等至良好收率的一系列多官能化喹啉。该程序通过将NH键顺序插入钯卡宾,分子内Heck反应和脱羧步骤进行。在此反应中,2-重氮苯基乙酸烷基酯充当C1的基本组成部分,是重氮化学的关键补充。
