Reaction of 3-R-chromones with dimedone and ammonium acetate leads to 2-(2-hydroxyaryl)-7,7-dimethyl-7,8-dihydroquinolin-5(6H)-ones (R = CF3CO, H), 3-(2-hydroxyaroyl)-7,7-dimethyl-7,8-dihydroquinolin-5(6H)-ones (R = CHO), and 8,8-dimethyl-8H-chromeno[2,3-b]quinoline-10,12(7H,9H)-diones (R = CN) depending on the nature of substituent R.
3-R-色酮与二甲酮和乙酸铵反应生成 2-(2-羟基芳基)-7,7-二甲基-7,8-二氢喹啉-5(6H)-酮 (R = CF3CO, H), 3- (2-羟基芳酰基)-7,7-二甲基-7,8-二氢喹啉-5(6H)-ones (R = CHO), 和 8,8-二甲基-8H-chromeno[2,3-b]quinoline-10 ,12(7H,9H)-二酮 (R = CN) 取决于取代基 R 的性质。
