Catalytic, Pyran, Furan, Tetrahydroquinoline, Synthesis
Catalytic performance of Lewis acids have been investigated in the synthesis of 1,2,3,4-tetrahydroquinolines via cyclocondensation reaction of aniline derivatives with cyclic enol ethers such as 3,4-dihydro-2H-pyran and 2,3-dihydrofuran. The catalytic activity of various of these catalysts in different solvents was compared with other classical catalysts such as KSF clay (1.5 g), InCl3 (10-20 mol%), ZrOCl2 (10 mol%), Sc(OTf)3 (3 mol%), PANI-InCl3 (10 mol%), I2 (20 mol%), InCl3 (5 mol%), 4-npa (25 mol%) and Cellulose-SO3H (0.03 g).
