Regioselective synthesis of 1,4-disubstituted imidazoles.
A short and efficient synthesis of 1,4-disubstituted imidazoles has been developed which provides the desired products with complete regioselectivity. This protocol allows preparation of compounds which are challenging to prepare by current literature methods in a regioselective fashion, a sterically and electronically diverse range of N-substituents being accessible. The sequence involves an u...
متن کاملSynthesis and Bleaching Activity of 1-Ethyl- and 1 -Propy 1-5-Substituted Imidazoles
Twenty-eight 1-ethyland l-p ropyl-5-substitu ted imidazoles were synthesized and their bleaching activity was evaluated by using the lettuce seedling test. 5-Phenyl1-propylimidazole (1) caused distinct chlorosis, while none o f the com pounds with various alkenyl groups at the 5-position o f the im idazole ring showed this bleaching activity. In troduction o f a brom o, chloro, fluoro, methyl o...
متن کاملcomparison of catalytic activity of heteropoly compounds in the synthesis of bis(indolyl)alkanes.
heteropoly acids (hpa) and their salts have advantages as catalysts which make them both economically and environmentally attractive, strong br?nsted acidity, exhibiting fast reversible multi-electron redox transformations under rather mild conditions, very high solubility in polar solvents, fairly high thermal stability in the solid states, and efficient oxidizing ability, so that they are imp...
15 صفحه اولSynthesis, characterization and photocatalytic activity of CeO2-SBA-15
Mesoporous photocatalysts of CeO2/SBA-15 are prepared by two methods of direct synthesis as solvent-usage and solvent-free methods. In solvent-usage method, CeO2/SBA-15 is synthesized in acidic media. While, in solvent-free method, CeO2/SBA-15, has been prepared through the novel path of directly grind cerium salt into the as-prepared samples of SBA-15 occluded ...
