Abstract A simple and novel synthesis of 1,2,3,4-tetrahydroquinoline derivatives by polyphosphoric acid–assisted reaction of N-aryl allyl anilines prepared from anilines has been reported. The generality and scope of the approach has been demonstrated by extending it to the synthesis of 1,2,5,6-tetrahydro-4H-pyrrolo[3,2,1-ij]quinoline (lilolidine) and 2,3,6,7-tetrahydro-1H,5H-pyrido[3,2,1-ij]quinoline

The reduction of quinolin-2(1H)-ones to 1,2,3,4-tetrahydroquinolines promoted by SmI2/Et3N/H2O is reported for the first time. This reaction involving the reduction of the amides proceeds through C−O bond cleavage. 1,2,3,4-Tetrahydroquinolines were obtained in mild conditions.
