- Microwave-assisted Synthesis of 2-methyl-4-quinolinones via combes synthesis catalyzed by acidic resin under solvent-free condition
-
A simple and efficient method for the synthesis of 2-methylquinolin-4(1H)- one derivatives using NKC-9-resin as reusable eco-friendly catalyst via Combes cyclization under solvent-free and microwave irradiation conditions is described. The quinolines were obtained in high yields and in short reaction times.

- 4,5-bis(dimethylamino)quinolines: Proton sponge versus azine behavior
-
Two first representatives, 5 and 6, of the still unknown 4,5-bis(dimethylamino)quinoline have been synthesized and studied. While the former, being protonated either at the peri-NMe2 groups or at the ring nitrogen, has been shown to display pro

- NaHSO4/SiO2: An efficient catalyst for the synthesis of β-enaminones and 2-methylquinolin-4(1H)-ones under solvent-free condition
-
An efficient and simplified protocol for NaHSO4/SiO2 catalyzed solvent-free synthesis of β-enaminone and 2-methylquinolin-4(1H)- one derivatives under microwave irradiation is described. A series of functionalized derivatives have been synthesized in shorter reaction times with moderate to good yields. The use of milder catalyst in non-conventional method offers significant advantages over conventional methods, such as higher selectivities, simplicity, solvent-free reaction and non-environmental polluting conditions.
