α-arylation of carbonylreaction and intra-molecular cyclization of 2-(2-bromophenyl)-1H-benzo[d]imidazoles with cyclohexane-1,3-diones was described in 1,4-dioxane catalyzed by Cu(I)/l-proline. It provided an efficient method for the synthesis of benzo[4, 5]imidazo[1,2-f] phenanthridin-4(1H)-ones with high efficiency in mild conditions.

A protocol for a copper-catalyzed intermolecular cross-coupling cascade between 2-(2-bromoaryl)-1H-benzo[d]imidazole analogues and proline or pipecolic acid has been developed. The developed protocol allows access to a variety of synthetically useful N-fused pyrrolo or pyrido[1,2-a]imidazo[1,2-c]quinazoline scaffolds with high efficiency and good functional group compatibility. Proline or pipecolic
