Abstract:An efficient strategy enabling the construction of polysubstituted 1,2-dihydroquinoline derivatives mediated by the commercially available, economical, and environmentally benign iodine (3 mol %) under mild conditions was developed. Various arylamines and α-ketoesters could participate in this cascade reaction, and the desired products were obtained in excellent yields up to 98%.
Keywords:Polysubstituted 1  2-dihydroquinoline  α-Ketoester  Arylamine  Iodine  Cascade reaction
