2-Aminobenzylalcohol reacts with an array of ketones in dioxane at 100 °C in the presence of a catalytic amount of CuCl2 along with KOH under O2 atmosphere to afford the corresponding quinolines in good yields. 2-Aminobenzylalcohol is also oxidatively coupled and cyclized with various aldehydes by step-by-step procedure, an initial treatment of 2-aminobenzylalcohol in the presence of CuCl2 and KOH
