A mild, efficient and highlyselective method for the synthesis of benzo[ F]quinoline derivatives via three-component reactions of arylaldehydes, naphthalen-2-amine and ketones or β-keto esters using iodine as catalyst is described. It should be noted that only one product was obtained, with high selectivity, when ketones or β-keto esters with two different α-hydrogen atoms were chosen as reactants

method for regioselective synthesis of C1-functionalised 3-arylbenzo[f]quinoline has been demonstrated via γ-selective aromatization using β-ketoester, 2-naphthylamine and aromatic aldehyde by employing 10 mol% camphorsulfonic acid as the catalyst in acetonitrile at 70 °C. In this approach, two C–C bond formations will result in functionalised benzo[f]quinoline in a one-pot three-component reaction
