series of new 4-(chromon-3-yl)-3-ethoxylcarbonyl-1,4,5,6,7,8-hexahydro-5-oxo-2,7,7- trimethylquinoline derivatives were synthesized from substituted 3-formylchromones, 5,5-dimethyl-1,3- cyclohexadione, am-monium acetate, and ethyl acetoacetate in a one-pot reaction. The structures of these compounds were characterized. The crystal structure of compound 2f was determined by X-ray single diffraction study, which belongs to monoclinic system with space P2/c and unit cell parameters: a＝2.0255(4) nm, b＝0.9132(2) nm, c＝1.4066(3) nm, β＝121.60(3)°, V＝2.2159(8) nm3, Z＝4, Dc＝1.335 g/cm3, μ＝0.209 mm－1, F(000)＝736, R1＝0.0556, wR2＝0.1248.
