  摘要：

  6-Ethyl-3-nitropyrano[3,2-c]quinoline-4,5(6H)-dione (4) was synthesized and its reactivity towards some 1,2-, 1,3-, and 1,4-binucleophiles was investigated. Ring transformation via opening of the gamma-pyrone ring and heterocyclizations through out these reactions led to certain interesting five, six, and seven-membered heterocyclic substituents, viz. pyrazolyl, pyridyl, pyrimidyl, diazepinyl, and thiazepinyl at position-3 of quinolin-2-one moiety.
