利用相转移催化法在超声辐射下合成了 8种未见文献报道的 5 ,7 二取代 2 (5 芳基 2 呋喃甲酰亚胺 ) [1,2 ,4] 噻二唑并 [2 ,3 a]嘧啶衍生物 .其结构经元素分析、IR和1HNMR得到确证 .该法具有操作简便 ,反应时间短等优点 .初步的生物活性测试结果表明部分化合物具有一定除草活性 .
Eight novel 5,7-disubstituted 2 (5-aryl-2-furancarboximides) [1,2,4] thiadiazolo [2,3] were synthesized using phase transfer catalysis under ultrasonic irradiation a] pyrimidine derivatives, the structure was confirmed by elemental analysis, IR and 1HNMR.The method has the advantages of simple operation, short reaction time, etc. The preliminary biological activity test results show that some compounds have certain herbicidal activity.
