The furoquinoline unit is present in many natural products. Here, an approach is presented for the preparing of furo[2,3-b]quinolines from readily available multi-substituted furans in the presence of Brønsted acid via an intramolecular cyclization under the heating conditions. Simple operation, good compatibility, high regioselectivity and morderate yields are the advantages of the method.

Key words: Brø, nsted acid, furo[2,3-b]quinoline, trifluoromethanesulfonic acid, Friedel-Crafts reaction
