An efficient method has been developed for the synthesis of benzofuro[3,2-b]quinolines through tandem [4+2] cycloaddition/ aromatization under transition-metal-free conditions. A range of aurone-derived N-tosyl-1-azadienes smoothly reacted with arynes, generated in situ via fluoride ion-induced 1,2-elimination of 2-(trimethylsilyl) aryl triflates, delivering structurally diverse benzofuro[3,2-b]quinolines in moderate to good yields.

Some benzofuroquinoline derivatives 1a-d and 3a were synthesized by condensation of 2-aminobenzaldehyde, 2-aminoacetophenone, 2-aminobenzophenone, isatin, or 2-aminobenzoic acid with 3(2H)-benzofuranone.The benzofuroquinolinone 3a was also obtained
