中文摘要:
      以(R)-2-(4-羟基苯氧基)丙酸为原料,经醚化、酰氯化、酰胺化或酯化等步骤合成了22个2-(4-芳氧苯氧基)丙酸酯或2-(4-芳氧苯氧基)丙酰胺化合物(Ⅳa~v),其结构经1HNMR、13CNMR、MS及EA表征。除草活性测试结果表明:在75 g/hm2浓度下,大部分化合物对单子叶杂草均具有选择性的除草活性,其中化合物Ⅳa、Ⅳc、Ⅳf、Ⅳg和Ⅳi对单子叶杂草(马唐、稗草、狗尾草)土壤处理和茎叶处理均具100%的防除效果。
英文摘要:
      Twenty two 2-(4-aryloxyphenoxy)propionic acid derivatives were designed and synthesized from (R)-2-(4-hydroxyphenoxy) propanoic acid, and their structures were characterized by 1HNMR, 13CNMR, HRMS or elemental analysis. The bioassay results indicated that most of the compounds exhibited excellent activities and selectivities against monocotyledonous weeds at 75 g/hm2. In particular, compounds Ⅳa, Ⅳc, Ⅳf, Ⅳg and Ⅳi exhibited 100% herbicidal efficiency in both pre- and postemergence treatments against Digitaria sanguinalis, Echinochloa crus-galli L and Setaria viridis.
