Synthesis of 2-arylquinazolin-4(3H)-one derivatives catalyzed by iodine in [bmim+][BF-4]

Wang, Xiang-Shan,Yang, Ke,Zhang, Mei-Mei,Yao, Chang-Sheng

experimental part, p. 2633 - 2646 (2010/10/03)

Controlling selectivity of the reactions of aromatic aldehydes and 2-aminobenzamide in ionic liquid catalyzed by iodine at either room temperature or at 80°C under nitrogen resulted in the synthesis of (E)-Schiff bases, 2,3-dihydro-2-arylquinazolin-4(1H)-one and 2-arylquinazolin-4(3H)-one derivatives, in excellent yields.
