Fast and Efficient Hantzsch Synthesis Using Acid-Activated and Cation-Exchanged Montmorillonite Catalysts under Solvent-Free Microwave Irradiation Conditions

摘要

An efficient and one-pot synthesis of dihydropyridine derivatives using acid-activated and cation-exchanged montmorillonite catalysts under solvent-free microwave irradiation conditions was described. The green, non-corrosive, non-toxic, and stable in air catalysts could be easily recycled and re-used without loss of catalytic activity.
