A simple synthesis of 4-alkylamino-6-chloroquinolines 5-9 from 5,8-dimethoxy-6-chloro-4(lH)quinolone J, is described. Thermolysis of arylaminomethylene Meldrum's acid derivative 2 is the key step on the preparation of compound 3. These compounds were tested in vitro against trypomastigote forms of Trypanosoma cruzi. Some derivatives were found to have a significant activity.
描述了从 5,8-二甲氧基-6-氯-4(1H) 喹诺酮 J 简单合成 4-烷基氨基-6-氯喹啉 5-9。芳基氨基亚甲基 Meldrum 的酸衍生物 2 的热解是制备化合物 3 的关键步骤。这些化合物在体外针对克氏锥虫的锥鞭毛体形式进行了测试。发现一些衍生物具有显着的活性。
