The synthesis of dicationic extended bis-benzimidazoles.
The synthesis of extended dicationic bis-benzimidazoles starting from trans-1,2-bis(4-cyanophenyl)ethene and trans-1,2-bis(4-cyanophenyl)cyclopropane is reported. The target diamidines show significant in vitro activity against B. subtilis.
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 اولParallel synthesis of 2-sulphanylated bis-benzimidazoles on soluble polymer support.
A well-sustained multistep synthetic protocol has been designed for the PEG-functionalized aromatic acid amide to generate a molecular library of 2-alkylthio bis-benzimidazoles. An attempted synthesis of benzimidazole-2-thiol in dichloromethane has led to S-chloromethyl methyl sulfides, mimicking bacterial enzymatic systems. Regioselective S-alkylation was brought about under controlled conditi...
متن کاملPEG1000-Based Dicationic Acidic Ionic Liquid/Solvent-Free Conditions: An Efficient Catalytic System for the Synthesis of Bis(Indolyl)methanes
An efficient procedure has been researched for the solvent-free synthesis of bis(indolyl)methanes via a one-pot reaction of indoles and aldehydes or ketones promoted by PEG1000-based dicationic acidic ionic liquid (PEG1000-DAIL). The catalyst PEG1000-DAIL could be reused seven times with excellent results. Furthermore, through this method, a highly chemoselective reaction of benzaldehyde and ac...
