Abstract
Cyclic enol ethers such as 3,4-dihydro-2H-pyran (DHP) and 2,3-dihydrofuran (DHF) undergo [4+2] cycloaddition reactions with imines (generated in situ from aryl amines and enol ethers) in the presence of 3 mol% scandium triflate immobilized in 1-butyl-3-methylimidazolium hexafluorophosphate under solvent-free conditions to afford the corresponding pyrano- and furo[3,2-c]quinolines in high yields.
