A rapid and efficient synthesis of 2-vinylquinolines via trifluoromethanesulfonamide-mediated olefination of 2-methylquinoline and aldehyde under microwave irradiation is reported. Biological evaluation of these scaffolds demonstrates that 2-vinylquinolines 3x-3z possess excellent antimalarial activities against chloroquine-resistant Dd2 strain of Plasmodium falciparum (IC50 < 100 nM).

A series of novel 4-subtituted amino-2-methylquinolines (3a-3o) were readily synthesized via the reaction of 4-chloro-2-methylquinoline with amines catalyzed by p-toluenesulfonic acid (TsoH) at 120 degrees C for 1 h under microwave-assisted organic synthesis (MAOS) condition. The yields of products 3a-3o were in range of 55-89%. This approach has advantages such as higher yield, shorter reaction time, lower costs, more convenience, and higher efficiency compared to the conventional method. The structures of the products were characterized by using H-1 NMR, C-13 NMR and HRMS. The reactivity of different amines was discussed.
