affordedthe corresponding thiourea derivative (V). Compound (V) was converted to thiazolidinone and thiazoline derivatives (VI) and (VII) by cyclocondensation with ethylbromoacetate or 4-chlorophenacylbromide, respectively. The synthesis of carbothioamide derivative (X) was performed starting from compound (II) by three steps. Treatment of compound (X) with sodium hydroxide, sulfuric acid, or chlorophenacyl
由3,4-二氟硝基苯制得的3-氟-4-(4-苯基哌嗪-1-基)苯胺(II)通过用4-甲氧基苯甲醛和吲哚-苯甲酸处理而转化为相应的席夫碱(III)和(IV)。 3-甲醛。用4-氟苯基异硫氰酸酯处理胺(II),得到相应的硫脲衍生物(V)。通过分别与溴乙酸乙酯或4-氯苯乙酰胺进行环缩合,将化合物(V)转化为噻唑烷酮和噻唑啉衍生物(VI)和(VII)。从化合物(II)开始,通过三个步骤进行碳硫酰胺衍生物(X)的合成。用氢氧化钠,硫酸或氯苯甲酰溴处理化合物(X),生成相应的1,2,4-三唑(XI),1,3,4-噻二唑(XII)和1,3-噻唑烷酮(XIII)衍生品。新化合物的结构分配基于其元素分析和光谱(IR,1H-NMR,13C-NMR和LC-MS)数据。在抗菌活性研究中,所有化合物均显示出高的耻垢分枝杆菌活性。
