CH-acidic compounds such as malonates 2a,b, ethyl cyanoacetate (2c), malononitrile (2d), ethyl acetoacetate (2e), acetylacetone (2f) or dimedone (2g) under mild conditions and good yields to quinolin-4-yl substituted derivatives 3-8 and 11. With 3-phenylsulfonylquinolones 1i-k a redox reaction to 2-hydroxy-2-quinolin-4-yl-malonates 9 was observed. Amination of 3-nitroquinolinyl malonate 3f leads to
4-氯或4-甲苯氧基喹啉1和10与CH酸性化合物反应,例如丙二酸酯2a,b,氰基乙酸乙酯(2c),丙二腈(2d),乙酰乙酸乙酯(2e),乙酰丙酮(2f)或二甲基酮(2g)在温和的条件下,对喹啉-4-基取代的衍生物3-8和11具有良好的收率。用3-苯基磺酰基喹诺酮类化合物1i-k,观察到对2-羟基-2-喹啉-4-基丙二酸酯9的氧化还原反应。3-硝基喹啉基丙二酸酯3f的胺化反应生成马洛酯酰胺13和14。
