A total of nine derivatives of 4-thiazolidinone were synthesized involving the reaction of benzene-1,2-
diamine with 4-aminobenzoic acid followed by reaction with substituted benzaldehyde to get the
Schiff bases. These synthesized Schiff bases were further reacted with thioglycolic acid to get the
desired thiazolidinones (29-37). In addition to conventional synthesis, the microwave irradiation method
has also been employedfor the synthesis of these compounds which provides not only pollution free
and eco-friendly environment but also excellent yields. The results showed that 2-substituted
thiazolidinone derivatives exhibit good antibacterial activity. It was also recorded that the compounds
containing -Cl, -NO2 group with thiazolidinone nucleus are more active than other compounds of the
synthesized series.
4-噻唑啉酮的九种衍生物总共被合成,包括苯-1,2-二胺与4-氨基苯甲酸反应,然后与取代苯甲醛反应得到席夫碱。这些合成的席夫碱进一步与巯基乙酸反应,得到所需的噻唑啉酮(29-37)。除了传统合成方法,还采用了微波辐射方法合成这些化合物,这不仅提供了无污染和环保的环境,而且产率也非常高。结果显示,2-取代噻唑啉酮衍生物表现出良好的抗菌活性。记录显示,含有-Cl,-NO2基团的噻唑啉酮核心化合物比合成系列中的其他化合物更活跃。
