以水杨醛为原料, 所得中间体2-(4,6-二甲氧基嘧啶-2-氧基)苯甲醛经三组分反应合成了12个2-[2-(4,6-二甲氧基嘧啶-2-氧基)苯基]-2-(取代苯胺)乙氰类化合物, 通过1H NMR, MS和元素分析对所合成的化合物进行了结构表征. 初步生物活性测试结果表明, 在试验浓度下合成化合物均具有良好的除草活性.

关键词: 4,6-二甲氧基嘧啶, 合成, 除草活性

Using 2-hydroxybenzaldehyde as starting material, twelve 2-[2-(4,6-dimethoxypyrimidin- 2-yloxy)phenyl]-2-(substituted aniline)acetonitrile derivatives have been synthesized by one-pot three- component reaction of 2-(4,6-dimethoxypyrimidin-2-yloxy)benzaldehyde intermediate. All synthesized compounds were confirmed by 1H NMR, MS techniques and elemental analysis. High herbicidal activities of all compounds were showed at preliminary bioassay.

Key words: 4,6-dimethoxypyrimidine, synthesis, herbicidal activity
