3-Fluoro-4-(morpholin-4-yl)aniline (2), prepared from 3,4-difluoronitrobenzene, was converted to the corresponding Schiff base (3) by treatment with indol-3-carbaldehyde. The treatment of thiourea 4 and carbothioamide derivatives 9 with ethyl bromoacetate or 4-substituted phenacyl bromides generated the corresponding thiazolidinone (5 and 13) and thiazoline (6 and 12) derivatives, respectively. The acidic or basic treatment of carbothioamide 9 produced 1,3,4-thiadiazole (11) or 1,2,4-triazole (10) compounds, respectively. The structural assignments of the new compounds were based on elemental analysis and spectral (IR, ^1H-NMR, ^13}C-NMR, and LC-MS) data. The antimicrobial activity study revealed that all compounds showed good antitubercular activities.
由3,4-二氟硝基苯制备的3-氟-4-(吗啉-4-基)苯胺(2),通过与吲哚-3-甲醛反应转化为相应的席夫碱(3)。通过硫脲4和卡巴肼衍生物9分别与溴乙酸乙酯或4-取代苯酰基溴反应,生成了相应的噻唑烷酮(5和13)和噻唑啉(6和12)衍生物。酸性或碱性处理卡巴肼9分别产生了1,3,4-噻二唑(11)或1,2,4-三唑(10)化合物。新化合物的结构鉴定基于元素分析和光谱(IR、¹H-NMR、¹³C-NMR及LC-MS)数据。抗微生物活性研究表明,所有化合物均显示出良好的抗结核活性。
