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 as C1 building block, which represents a key compliment to diazo chemistry.

钯催化2-（1-芳基乙烯基）苯胺和α-重氮羰基化合物对多官能喹啉的[5 + 1]环化

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，以中等到良好的产率提供了一系列多官能化的喹啉。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。在该反应中，2-重氮苯基乙酸烷基酯用作C1结构单元，代表了对重氮化学的关键补充。
