3-thiazol-2-amines by a twostep reaction sequence involving formation of 2-bromo-1- (polyfluoroaryl)propan-1-ones under the acidic bromination conditions followed by heterocyclization with thiourea to finally afford new 5-methyl-4-polyfluoroaryl-1,3-thiazol-2- amines in high yields. 1,1-(2,3,5,6-Tetrafluoro-1,4-phenylene)- dipropan-1-one was involved in the similar reaction to give a derivative containing
通过涉及形成 2-溴-1-(多氟芳基)丙-1 的两步反应序列将 1-(多氟芳基)丙-1-酮转化为 5-甲基-4-多氟芳基-1,3-噻唑-2-胺-ones在酸性溴化条件下,然后用硫脲杂环化,最终以高产率提供新的5-甲基-4-多氟芳基-1,3-噻唑-2-胺。 1,1-(2,3,5,6-四氟-1,4-亚苯基)-二丙烷-1-酮参与类似的反应,得到含有两个噻唑部分的衍生物。
