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.

The palladium-catalysed cross-coupling reactions of arylboronic acids with a variety of pi-deficient heteroaryl chlorides proceed in high yield. [1,4-Bis(diphenylphosphino)butane]palladium(II) dichloride was found to be a very satisfactory catalyst for monocyclic heteroaryl chlorides, whereas tetrakis(triphenylphosphine)palladium(O) was found to be excellent for a range of chloroquinoline derivatives.
