Herein is reported a substantially improved synthesis of 2-substituted benzimidazoles by condensation of 1,2-diaminoarenes and aldehydes using methanol as the reaction medium. The developed method afforded moderate to excellent yields (33–96%) at ambient temperature, displays high functional group tolerance, is conducted open to air, and requires only one minute reaction time under catalyst- and additive-free
This invention relates to a family of benzimidazole analogs, which are inhibitors of the IgF response to allergens. These compounds are useful in the treatment of allergy, asthma, or any diseases where IgE is pathogenic.
This invention relates to a family of diacyl benzimidazole analogs, which are inhibitors of the IgE response to allergens. These compounds are useful in the treatment of allergy and/or asthma or any diseases where IgE is pathogenic. They have the following general structure

A simple an expeditious method was established for the synthesis of 2-Substituted-1H-Benzimidazole derivatives at 90 degrees C using o-phenylenediamine and different aldehydes. It has been found that a mixture of Methanesulphonic acid-SiO2 to be an effective catalyst to generate moderate to high yield of a wide variety of 2-substituted benzimidazole derivatives through a simple workup process. Solid phase, rapid reaction, solvent free technique and simplicity of the reaction procedure are the advantages of this protocol.
