The possibility of synthesis of quinoline[1,2-a]benzimidazole from aniline and quinoline on a dehydrogenating mark K-16 catalyst at 560-580°C was demonstrated. It was established that in the nitration of quinolino[1,2-a]benzimidazole, a 10-nitro-derivative is formed, whereas in the reaction with ADCE, tetramethoxycarbonylquinolino[1,2-a]pyrido[2′,1′-b]benzimidazole is formed. 1996 Plenum Publishing Corporation.

An efficient copper(I)-catalyzed direct regioselective arylamination of various heterocyclic N-oxides was achieved successfully under redox-neutral conditions using anthranils as arylaminating reagents. The developed protocol is simple, straightforward, and economic with a broad range substrate scope. The dual functional groups in the final molecules were utilized to construct structurally and functionally diverse nitrogen-containing organic π-conjugated systems.

An efficient method for the synthesis of benzimidazo[1,2-a]quinolines under transition-metal-free conditions has been developed through a cascade reaction involving sequential aromatic nucleophilic substitution and intramolecular Knoevenagel condensation reactions. This method is applicable for the synthesis of a wide range of benzimidazo[1,2-a]quinoline derivatives from readily available 2-fluoroarylaldehyde and benzimidazole substrates.
