A multiple synthetic strategy is employed to furnish the synthesis of 6, 12, 18-triaryldibenzo[b, j]quinoline[2, 3-f] [1, 7]phenanthroline. The key intermediate 6, 12, 18-trichlorobenzotriquinoline was prepared by Buchwald-Hartwig reaction of 1, 3, 5-tribromobenzene with methyl anthranilate, followed by hydrolysis and POCl3-promoted ring closure reaction. The palladium-catalyzed Suzuki coupling was carried out with a novel catalyst Pd-132 to form fourteen C3-symmetric 9-aryl acridine derivatives. The reactions can be performed at low catalyst loading (0.1 mol%, ca. 0.03 mol% per site).

Key words: Buchwald-Hartwig reaction, acridine, Pd-132, Suzuki coupling
