One-pot synthesis of substituted pyrano- and furano[3,2-c]quinoline derivatives from appropriately substituted anilines, substituted benzaldehydes and dienophiles via Povarov reaction catalyzed by HCl-ethanol were reported.Good to excellent yields with high diastereoselectivity were obtained in all entries tested.
