A highly efficient method for the synthesis of fluorinated 1,3,5-triaryltriazine derivatives is developed by the condensation reaction of aromatic amines and formaldehyde followed by spontaneous cyclotrimerization using task-specific 1,1,3,3-tetramethylguanidine trifluoroacetate [TMG][Tfa] ionic liquid as a environmentally benign solvent in excellent yields at room temperature. The synthesized compounds were subjected for in vitro antitubercular activity against Mycobacterium tuberculosis H37Rv strain using the Löwenstein–Jensen medium.
高效合成氟化1,3,5-三芳基三嗪衍生物的方法是通过芳香胺与甲醛的缩合反应,随后在室温下使用特定任务的1,1,3,3-四甲基胍三氟乙酸盐[TMG][Tfa]离子液体作为环境友好型溶剂进行自发环三聚化,产率优异。所合成的化合物在Löwenstein-Jensen培养基中针对结核分枝杆菌H37Rv株进行了体外抗结核活性测试。
