structural feature of many natural products. By using a domino reaction of aromatic amines and cyclicenolethers or 2-hydroxy cyclicether catalyzed by indium chloride in water, various tetrahydroquinoline derivatives were synthesized efficiently. Most cyclization products showed cis selectivity. The use of 2,3-dihydrofuran as the cyclicenolether provided both higher reactivity and cis selectivity than
