A novel synthetic route has been designed to introduce fluorine functionality into a series of compounds containing thiazolidin-4-one rings. These compounds were synthesised from various aniline derivatives using a two-step approach: an addition reaction of ethyl isothiocyanate with different aromatic fluorinated anilines, followed by cyclisation to yield the final products. A total of 15 novel fluorinated
设计了一种新的合成路线,将氟官能团引入一系列含有噻唑烷-4-酮环的化合物中。这些化合物是采用两步法从各种苯胺衍生物合成的:异硫氰酸乙酯与不同的芳香族氟化苯胺进行加成反应,然后环化产生最终产品。总共合成了 15 种新型氟化噻唑烷酮化合物,并使用1 H NMR、 19 F NMR、傅里叶变换-红外、元素分析和液相色谱-质谱法进行了表征。使用核奥沃豪塞效应光谱法测定了合成衍生物中亚胺键周围的立体化学。针对两种人类癌细胞系:肝癌细胞 (HepG2) 和结肠癌细胞 (HCT116) 测试了这些化合物的体外抗癌潜力。研究表明,与邻位和对位的衍生物相比,在芳环的间位具有氟官能团的衍生物显示出良好的抗癌潜力。
