    嘌呤氧基苯氧丙酸酯的合成及除草活性

    Synthesis and biological activities of purinoxy-phenoxy- propionate derivatives

      摘要
    • 摘要: 以4,6-二氯-5-硝基嘧啶为起始原料,经过还原胺化、取代、醚化等一系列反应,得到11个未见文献报道的嘌呤氧基苯氧丙酸酯类化合物1a~1k,其结构经1H NMR和MS确认。初步生物活性测定表明:在200 mg/L下,所有目标化合物均表现出一定的除草活性,其中化合物1f ((R)-2-(4-((9-(4-氯苯)-8-(三氟甲基-9H-嘌呤-6-基)氧)苯氧)丙酸丁酯)和1h ((R)-2-(4-((9-(4-氯苯)-8-(三氟甲基-9H-嘌呤-6-基)氧)苯氧)丙酸乙酯)对靶标的抑制率几乎都达到100%。

       

      Abstract: Using 4,6-dichlone-5-nitro pyrimidine as starting material, 11 novel purinoxy-phenoxy- propionate derivatives 1a-1k were synthesized by reductive amination, substitution and etherification. Structures were characterized by 1H NMR and MS spectra. Preliminary results showed that all of compounds displayed herbicidal activities at the concentration of 200 mg/L. The inhibition rate of 1f ((R)-butyl-2-(4-((9-(4-chlorophenyl)-8-(trifluoromethyl-9H-purin-6-yl)oxy)phenoxy)propanoate) and 1h ((R)-ethyl-2-(4-((9-(4-chlorophenyl)-8-(trifluoromethyl-9H-purin-6-yl)oxy)phenoxy)propanoate) almost reached 100%.
