Montmorillonite modified as an efficient and environment friendly catalyst for one- pot synthesis of 3, 4-dihydropyrimidine-2(1H) ones

Montmorillonite modified is an efficient environmental friendly catalyst under one-pot-three-component synthesis of 3,4-dihydropyrimidine-2(1H) ones. The preparation was performed with an aldehyde, 1,3-dicarbonyl compounds, urea or thiourea under solvent-free conditions. In comparison with the other methods of Biginelli reaction, this new method has short reaction time inexpensive catalyst and ...

Nano Al2O3: An efficient catalyst for the multi-component synthesis of Pyrano [2, 3-d] Pyrimidinone derivatives

Pyrano [2,3-d] pyrimidinone derivatives have received considerable interest from the pharmaceutical industry due to their wide range of interesting biological and therapeutic properties. Nano Al2O3 was found to be a highly efficient solid acid catalyst for the preparation of pyrano [2,3-d] pyrimidinone derivatives from the reaction of barbituric acid, aryl aldehyde and mal...
