Abstract

Broensted Acidic Ionic Liquid-Catalyzed One-Pot Synthesis of 3,4-Dihydropyrimidin-2(1H)-ones and Thiones under Solvent-Free Conditions. -An ionic liquid-catalyzed Biginelli reaction under solvent-free conditions is presented. Both aliphatic and aromatic aldehydes as well as urea and thiourea react smoothly under given conditions. -(HAJIPOUR*, A. R.; KHAZDOOZ, L.; ZAREI, A.; Synth.
