moclobemide is a selective and reversible monoamine oxidase-a inhibitor, which is used as an antidepressant. three moclobemide analogues were synthesized by replacing moclobemide phenyl ring with substituted imidazoles. so, n-[(4-morpholinyl) ethyl)]-1-benzyl-2-(alkylthio)-1h-imidazole-5-carboxamides (7a-c) were synthesized and studied for the antidepressant activity using forced swimming test ...

Easy accessible isoxazol-5(4 H )-ones are useful precursors of heterocycles. In this context we report the ruthenium-catalyzed transformation 4-alkenyl-substituted isoxazol-5-ones to afford 1 -pyrrole derivatives. The operative conditions were proven be effective also on cyclohexane-fused isoxazolones giving 4,5,6,7-tetrahydroindoles. Reactions, which allow access tri-and tetra-substituted pyrr...

The title mol-ecule, C35H25N3O, is a tri-phenyl-amine derivative with the 4-position substituted by an aldehyde group, and the 4'-position substituted by a 6-phenyl-2,2'-bi-pyridine group. The whole mol-ecule is non-planar and the dihedral angle between the core benzene and pyridine rings is 36.96 (5)°. The dihedral angle between the phenyl and benzaldehyde groups bonded to the amine N atom is ...

Quaternisation of 3,5-diaryl-1,2,4-thiadiazoles with trimethylsilylmethyl triflate at 40 8C occurred at N-2. Separate desilylation of the salts resulted in a ring expansion to substituted 2H-1,3,5-thiadiazines 5. Heating of these with ethanolic sodium ethoxide caused sulfur extrusion and ring contraction to 2,4-disubstituted imidazoles 6. 3,4-Diaryl1,2,5-thiadiazoles were less reactive to alkyl...

γ-Alumina nano particle catalyzed multi component reaction of benzil, arylaldehyde and aryl amines afforded the highly substituted 1,2,4,5-tetraaryl imidazoles with good to excellent yield in less reaction time under the sonication as well as the conventional methods. Convenient operational simplicity, mild conditions and the reusability of catalyst were the other advantages of this developed p...

[Structure: see text] Enantioselective nitrone cycloadditions with beta-substituted alpha,beta-unsaturated 2-acyl imidazoles catalyzed by bis(oxazolinyl)pyridine-cerium(IV) triflate complexes 1 have been reported. The isoxazolidine products were efficiently transformed into densely functionalized beta'-hydroxy-beta-amino acid derivatives.
