Seven hexahydrodispiro[indole-3,3′-indolizine-2′,3″-piperidine]-2(1H),4″-dione compounds were synthesized by a catalyst-free 1,3-dipolar cycloaddition reaction in a one-pot three-component system containing 3,5-diarylidene-1-benzylpiperidin-4-one, isatin and l-pipecolic acid. The structures of these compounds were characterized by nuclear magnetic resonance, high-resolution mass spectrometry and X-ray
七种六氢二螺[indole-3,3'-indolizine-2',3"-piperidine]-2(1H),4"-二酮化合物通过无催化剂的1,3-偶极环加成反应在一锅法中合成包含 3,5-diarylidene-1-benzylpiperidin-4-one、靛红和 l-哌啶酸的三组分系统。这些化合物的结构通过核磁共振、高分辨率质谱和X射线数据分析进行表征。对这些化学实体的细胞毒性进行了评估(盐水虾测定),并发现五种化合物在该生物测定中具有潜力。化合物 2e 是最突出的抗盐卤虫靶标,LC50 值为 7.27 μg/mL。
