CuO nanoparticles were found to be efficient catalysts for the synthesis of quinazoline derivatives; twenty-four products were obtained with good to excellent yields via reaction of N-arylamidines and aromatic aldehydes or benzyl alcohol in air. Neither a base nor an organic oxidant was necessary, and CuO nanoparticles can be recycled without a significant decrease in catalytic activity.
OBJECTIVES We previously reported a series of quinazoline derivatives as vascular-targeting anticancer agents. In this study, we investigated the mechanism underlying the anti-angiogenic activity of the quinazoline derivative compound 11d. MATERIALS AND METHODS We examined the effects of quinazoline derivative 11d: on vascular endothelial growth factor receptor-2 (VEGFR2) activation via VEGFR...
White-light emission from single molecular systems has attracted a great deal of attention due to their advantages over multicomponent emitters. Azaheterocyclic push-pull derivatives have been demonstrated be white emitters by combining neutral and protonated forms in the appropriate ratio, although limited cases white-light reported quinazoline derivatives. Herein, we describe series 4-substit...
New quinazoline derivatives were prepared by one pot reaction of anthranilic acid, acetic anhydride and primary amines, under ultrasonic irradiation. As a result, Ultrasonic irradiation has led to affordable, clean synthesis of a variety of target compounds in much higher yields, than traditional methods. This method has numerous advantages: such as higher yields, shorter reactions time, and ea...
