for different reaction times gave five products which were formed by the progressive degradation of the nitropyrano ring. Varying amounts of 3-nitroacetylquinolinones, quinolinones with side-chains of β- and α-ketoacids, quinolinone-3-carboxylic acids and 4-hydroxyquinolinones were isolated. With the aim of preparing new biologically active quinolone derivatives, the products of reaction of the 3-ni
3-硝基吡喃喹啉酮(6-烷基-4-羟基-3-硝基-2H-吡喃并[3,2-c]喹啉-2,5(6H)-二酮)碱水解不同反应时间得到五种产物通过硝基吡喃环的逐渐降解。分离出不同数量的 3-硝基乙酰喹啉酮、具有β-和α-酮酸侧链的喹啉酮、喹啉酮-3-羧酸和4-羟基喹啉酮。为了制备新的生物活性喹诺酮衍生物,还研究了 3-硝基吡喃喹啉酮与 β- 和 α-酮酸侧链与一些氮和碳亲核试剂的反应产物,一些产生了环化产物。
