متن کاملApplication of Sulfonic Acid Functionalized Nanoporous Silica (SBA-Pr-SO3H) in the Green One-pot Synthesis of Polyhydroacridine Libraries
1,8-Dioxo-decahydroacridines have been synthesized by the three-component reaction of aromatic aldehydes, aromatic amines (or ammonium acetate), and dimedone in the presence of sulfonic acid functionalized nanoporous silica (SBA-Pr-SO3H) under solvent-free conditions. Excellent yields, short reaction times, mild reaction conditions, an...

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...
