  Halogenation reactions in position 3 of quinoline-2,4-dione systems by electrophilic substitution and halogen exchange

  摘要：

  3-Substituted 4-hydroxy-2(1 H)-quinolones 3, 5, 7 are halogenated with bromine or sulfuryl chloride to yield the quinolinediones 9 or 10. Reaction of 3, 5, 7 with chloroform gives the dichloromethyl quinolinediones 11. Halogen exchange leads from the chloro quinolinediones 10 to fluoro quinolinedones 12 and to azido quinolinediones 13. Similarly the dichloro quinolinedione 10 an reacts to the difluoro quinolinedione 14, which is reduced to the 3-fluoro-4-hydroxyquinolone 16 and reacts again with sulfuryl chloride to give the mixed 3-chloro-3-fluoroquinolinedione 15.

  Nitration of 3-substituted-4-hydroxy-2(1H)-quinolones 1 with nitric acid leads either to 3-nitro- 2 or 3-hydroxyquinolinediones 3, depending on the reaction conditions. 3-Substituted-3-hydroxyquinolinediones 3 are also obtained by oxidative hydroxylation with peracetic acid. Amination of 3-substituted-3-chloroquinolinediones 4 with ammonium hydroxide predominantly leads again to 3-substituted-3-hy

  根据反应条件，用硝酸硝化3-取代的-4-羟基-2（1 H）-喹诺酮1可以生成3-硝基-2或3-羟基喹啉二酮3。3-取代的-3-羟基喹啉二酮3也可以通过用过乙酸氧化羟基化而获得。用氢氧化铵胺化3-取代的3-氯喹啉二酮4主要再次导致3-取代的-3-羟基喹啉二酮3，仅在一种情况下可以分离3-氨基喹啉二酮5。用吗啉或吡啶作为胺，获得了预期的3-氨基喹啉二酮6和7。
