چکیده
in this work, a green, simple and highly efficient procedure for the synthesis of bis(indolyl)methanes is described. the condensation of indoles with carbonyl compounds catalyzed by citric acid in water affords bis(indolyl)methanes in high yields and relatively short reaction times. the advantages of this method are using of water as a low cost solvent and efficient recyclability of the catalyst.

β-Cyclodextrin sulfuric acid as a green Lewis acid catalyst has been applied for the preparation of bis(indolyl)methanes, tris(indolyl)methanes and 3,3'-diindolyloxindole derivatives by the condensation of indoles with various carbonyl compounds in aqueous media with high to excellent yields.
متن کاملGreen synthesis of bis(indolyl)methanes in water using sulfonic acid functionalized silica (SiO2-Pr-SO3H)
Bis(indolyl)methanes are important group of bioactive metabolites of terrestrial and marine regions. They were synthesized by different methods. Herein, a clean, one-pot synthesis of bis(indolyl)methane derivatives by cyclo-condensation reaction of indole and various aldehydes using Sulfonic acid functionalized silica (SiO2-Pr-SO3H) in aqueous media is reported. The advantages of this new metho...
