December 7, 2011A series of substituted benzimidazoles and benzothiazoles were prepared through the one-pot reaction of o-phenylenediamine and o-aminothiophenol with various aldehydes in the presence of ferric hydrogensulfateboth in EtOH and water as solvent. The reactions proceed smoothly in excellent yield, high chemoselectivityand with an easy work-up.Key Words : Benzimidazole, Benzothiazole, Fe(HSO
A Novel Ionic Liquid Based on Imidazolium Cation as an Efficient and Reusable Catalyst for the One-pot Synthesis of Benzoxazoles, Benzthiazoles, Benzimidazoles and 2-Arylsubstituted Benzimidazoles
A novel dicationic ionicliquid based on imidazolium cation is designed, synthesized and successfully used as catalyst for the one‐potsynthesis of benzoxazoles, benzthiazoles, benzimidazoles and 2‐arylsubstituted benzimidazoles. The remarkable feature of this new catalyst is its ethyleneoxy bridge which participates in dissolving organic compound in ionicliquid. The application of this ionic liquid

(MAO-B), cyclooxygenase-1 (COX-1) and cyclooxygenase-2 (COX-2) enzyme inhibitory, and antimicrobial activities of a new series of 2-(4-substituted phenyl)-1-[2-(morpholin-4-yl)ethyl]-1H-benzimidazole derivatives, for their possible use as multi-action therapeutic agents. Target compounds (n = 15) were synthesized under microwave irradiation conditions in two steps, and their structures were elucidated

A colored resin composition is provided which is capable of providing blue pixels of a color filter that have excellent light resistance and which satisfies heat resistance required in color display production steps. A color filter having blue pixels with excellent color purity and transmittance and an organic EL display and a liquid-crystal display device both having satisfactory blue purity are also provided by using the colored resin composition. The colored resin composition for color filter includes (a) a binder resin, (b) a solvent, and a triarylmethane type coloring matter of a specific structure represented by general formula (I). The color filter, organic EL display, and liquid-crystal display device are produced using the colored resin composition.
Substituted-3H-indeno[1,2-c]pyridazin-3-ones, substituted-3H-indeno[1,2-c]pyridazin-3-thiones, and pharmaceutically acceptable salts thereof are disclosed. Methods of preparing the same are also disclosed. The compounds are useful as cardiotonic and antihypertensive agent.
