The synthesis of new indazol-4,7-dione derivatives via 1,3-dipolar cycloaddition of diazomethane with 2,3-dimethyl-1,4-benzoquinone (2) and 1,4-naphthoquinone (7) followed by N-alkylation of the pyrazol nitrogen atom of the corresponding quinones (3) and (8) with methyl chloroacetate is described. A series of amides from esters (5) and (10) were also obtained. These compounds were tested in vitro as
通过重氮甲烷与1,3-二甲基-1,4-苯醌(2)和1,4-萘醌(7)的1,3-偶极环加成反应,然后进行N-烷基化反应,合成新的吲唑-4,7-二酮衍生物描述了相应的醌(3)和(8)的吡唑氮原子与氯乙酸甲酯的关系。还从酯(5)和(10)获得了一系列酰胺。这些化合物作为潜在的抗锥虫药物进行了体外测试。发现化合物(4)和(8)具有明显的活性。
