Abstract
Montmorillonite K10 is a suitable catalyst in a multicomponent reaction involving an aldehyde, an amine, and thioglycolic acid in N,N-dimethylformamide as solvent at moderate (50°C) to reasonably high (120°C) temperatures to form thiazolidinones. The reaction involves easy workup and purification. Several thiazolidinones were prepared. In particular, campholenic aldehyde obtained from α-pinene was used to synthesize potentially bioactive thiazolidinones. All products were characterized by IR, 1H NMR, and mass spectra. Preliminary anticancer screening tests revealed that two compounds show anticancer activity and can be taken up for further screening.
摘要Montmorillonite K10是在N,N-二甲基甲酰胺作为溶剂下,适用于涉及醛、胺和巯基乙酸的多组分反应的催化剂,在中等(50°C)到相当高(120°C)的温度下形成噻唑烷酮。该反应易于操作和纯化。制备了几种噻唑烷酮。特别地,从α-蒎烯中获得的香松醛被用于合成潜在的生物活性噻唑烷酮。所有产物均通过红外、1H NMR和质谱进行了表征。初步的抗癌筛选测试表明,两种化合物表现出抗癌活性,可以进一步筛选。
