In order to find active pesticide leading compounds, thinking about that triazolothiadiazoles had various biological activities, this paper designed and synthesized 11 novel title compounds from 3-substituted-4-amino-5-mercapto-1,2,4-triazoles with heterocyclic carboxylic acid via cyclization in the presence of phosphoryl chloride by the princple of combination of active strucural moieties. The structures of the title compounds were characterized by melting point, IR, 1HNMR and elemental analysis.
为了寻找高活性农药先导化合物,考虑到三唑并噻二唑衍生物具有广泛的生物活性,本文利用活性亚结构拼接原理,将活性基团分别引入1,2,4-均三唑并[3,4-b]-1,3,4-噻二唑杂环的3位和6位,合成了未见文献报道的3,6-二取代均三唑并[3,4-b]-1,3,4-噻二唑类化合物11个,并用IR、1HNMR及元素分析测试技术对其进行了结构表征。
