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.
