Unsymmetric, N-substituted benzimidazoles and imidazopyridines can be prepared directly from 2-halonitroarenes and amides through Pd(TFA) 2/(R)-BINAP-catalyzed cross-coupling and subsequent reductive aminocyclization. This sequence can be conducted by a one-pot procedure. The method is versatile and allows the straightforward, regioselective preparation of these important nitrogen heterocycles.

Page/Page column 21-22, (2008/06/13)
The present invention relates to a process for the regioselective synthesis of compounds of the formula I, wherein R0; R1; R2; R3; R4; R5; A1; A2; A3; A4, Q and J have the meanings indicated in the claims. The present invention provides a direct palladium catalyzed, regioselective process to a wide variety of unsymmetrical, multifunctional N-substituted benzimidazoles or azabenzimidazoles of formula I starting from 2-halo-nitroarenes and N-substituted amides useful for the production of pharmaceuticals, diagnostic agents, liquid crystals, polymers, herbicides, fungicidals, nematicidals, parasiticides, insecticides, acaricitdes and arthropodicides.
Novel Antagonists of Platelet-Activating Factor. 1. Synthesis and Structure-Activity Relationships of Benzodiazepine and Benzazepine Derivatives of 2-Methyl-1-phenylimidazopyridine
