由含不同取代基的水杨醛与乙酰乙酸乙酯在哌啶存在下反应, 得到乙酰基香豆素中间体, 再与氨基硫脲缩合, 得到含香豆素基的缩氨基硫脲化合物, 继而与α-溴代芳基酮发生缩合反应, 合成了9个未见报道的新的N-(4-取代苯 基-噻唑-2-基)香豆素类亚胺化合物, 其结构用IR, 1H NMR和HRMS进行了确证, 初步生物活性测定实验证明部分目标化合物具有良好的抑菌活性.

Nine new N-(4-substituted phenylthiazol-2-yl)coumarins were synthesized via the condensation of aminothiourea with acetyl coumarin intermediates, which were generated by the reaction of substituted salicyladenydes with ethyl acetoacetate, and sequeutial reaction with α-bromoarylketones. These compounds exhibit good antimicrobial activities. The structures of the products were established by IR, 1H NMR and HRMS techniques.

Key words: thiosemicarbazone, N-(4-substituted phenylthiazol-2-yl) coumarins, antibacterial activity, synthesis
