为了寻找新型高活性的除草剂先导化合物, 采用活性亚结构连接法, 利用Ugi反应将3-三氟甲基苯甲酰基、2-(取代苯氧)丙酰基和2-(4,6-二甲氧基嘧啶-2-氧基)苯甲酰基等除草活性结构片段与3-三氟甲基苯基引入到同一分子中, 合成了一系列2-{N-(3-三氟甲基苯基)-[3-(三氟甲基)苯甲酰、2-(取代苯氧)丙酰、2-(4,6-二甲氧基嘧啶-2-氧基)苯甲酰]-氨基}-取代苯乙酰环己胺3a3i, 采用IR, 1H NMR, EI-MS和元素分析对其结构进行了表征. 初步的除草活性测试结果表明: 部分化合物在100 mg/L浓度下对油菜显示出中等至良好的除草活性. 温室盆栽测试结果显示部分化合物在1.5 kg/ha剂量下, 在苗前处理时对油菜、反枝苋、稗草和马唐具有良好的除草活性.

In order to find novel high active herbicidal lead compound, a series of N-cyclohexyl 2-{N-(3-trifluoromethyl-phenyl)-[3-(trifluoromethyl)benzoyl, 2-(substitutedphenoxy)propionyl, 2-(4,6-dimethoxypyrimidinyl-2-oxy)benzoyl]-amino}-substitutedphenylacetamides 3a3i were designed and synthesized by introducing 3-trifluoromethylbenzoyl, 2-aryloxy-pro-pionyl or 2-(4,6-dimethoxypyrimidin-2-yloxy)benzoyl and 3-trifluoromethyl phenyl moieties into the molecular skeleton via the Ugi reaction. Their structures were characterized by IR, 1H NMR, EI-MS, and elemental analyses. The preliminary bioassay (in vitro) indicated that some of compounds 3 displayed moderate to good herbicidal activity against Brassica campestris L at the concentration of 100 mg/L. The glasshouse bioassay (in vivo) showed that some of compounds 3 exhibited good herbicidal activities against B. campestris, A. retroflexus, E. crusgalli and D. sanguinalis in pre-emergence treatment at a dose of 1500 g/ha.

Key words: Ugi reaction, pyrimidinyl salicylic acid, aryloxy propanoic acid, phytoene desaturase (PDS) inhibitor, herbicidal activity
