以砜基取代的嘧啶为关键中间体,设计合成了17个新型取代苯氧基1,2,4-***并[1,5-a]嘧啶类衍生物,通过元素分析、MS和~1H NNIR对所合成的化合物进行了结构表征.初步生物活性测定结果表明,100 mg/L浓度下部分化合物对6种测试靶标均表现出较好的抑制活性,盆栽复筛试验显示在150 g/hm~2剂量下,5个化合物表现出较好的除草活性和持效性.

Seventeen novel substitued phenzoxy 1,2,4triazolopyrimidine derivatives have been designed and synthesized using sulfone substituted 1,2,4-triazolo pyrimidine as starting material.All synthesized compounds were confirmed by elemental analysis,MS and ^1H NMR.Preliminary bioassay indicates that some of them display good herbicidal activities at concentration of 100 mg/L.Five compounds exhibited good herbicidal activit...
