Diversity: A range of substituted 2‐alkylquinolines can be prepared in a general and efficient synthetic approach that employs mild reaction conditions (see scheme). The synthesis is based on a sequential palladium‐catalyzed CN and CCbondformation, followed by palladium‐catalyzed aromatization, and results in the formation of the desired compounds in one step.
