摘要
A palladium-catalyzed [5+1] annulation of 2-(1-arylvinyl) anilines and alpha-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.
