multitargeting agents. The N-alkylation of imides and O-alkylation of phenols are important reactions frequently used in the synthesis of biologically active compounds, like the thiazolidine-2,4‑dione derivatives. Based on literature data, by treating (Z)-5-(4-hydroxybenzylidene)-thiazolidine-2,4‑dione with alkyl halides in a 1:1 molar ratio, either O-alkylation or N-alkylation reactions can take place. Six
噻唑烷-2,4-二酮代表药物化学中的关键杂环核心,因为它具有与多种蛋白质靶标结合的能力,并且已被广泛研究以开发生物活性多靶标试剂。酰亚胺的N-烷基化和酚的O-烷基化是生物活性化合物(如噻唑烷-2,4-二酮衍生物)合成中经常使用的重要反应。根据文献数据,通过用烷基卤化物以1:1的摩尔比处理(Z)-5-(4-羟基亚苄基)-噻唑烷-2,4-二酮,可以进行O-烷基化或N-烷基化反应。通过将(Z)-5-(4-羟基亚苄基)-噻唑烷-2,4-二酮与脂肪族卤代衍生物在碱性条件下烷基化,合成了六种(Z)-5-(4-羟基亚苄基)-噻唑烷-2,4-二酮衍生物环境,使用1:摩尔比为1,然后进行物理和光谱分析。光谱数据和从母体化合物的酸度的理论评价获得的结果支持在反应条件下N-烷基化衍生物的形成。
