A short new route to the pyrido[2,3,4-kl]acridine ring system has been developed from readily available quinoline precursors involving two key steps: (i) a palladium(0)-catalysed Suzuki cross-coupling reaction of 4-chloroquinolines with arylboronic acids, and (ii) an intramolecular nitrene insertion reaction of the nitrenes derivedfrom 4-phenyl-5-azidoquinolines.
