A direct, regioselective palladium-catalyzed synthesis of N-substituted benzimidazoles and imidazopyridines

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.

Structure-guided design of substituted aza-benzimidazoles as potent hypoxia inducible factor-1α prolyl hydroxylase-2 inhibitors

We report the structure-based design and synthesis of a novel series of aza-benzimidazoles as PHD2 inhibitors. These efforts resulted in compound 22, which displayed highly potent inhibition of PHD2 function in vitro.

A regioselective palladium catalyzed synthesis of benzimidazoles and azabenzimidazoles

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

Following the discovery of moderately potent antagonist activity against platelet-activating factor (PAF) in 2-methyl-1-phenylimidazopyridine (2) (IC50=840 nM), 19 derivatives (3-21) were prepared which incorporated various lipophilic groups attach
