Two series of novel (Z)‐nitenpyram analogs 2a, 2b, 2c, 2d, 2e, 2f, 2g, 2h, 3a, 3b, 3c, 3d were synthesized by introducing various amino acids benzyl ester or amino acids tetrahydrofurfur‐2‐yl ester into nitenpyram and forming a tetrahydropyrimidine ring to fix (Z)‐configuration. The structures of the target compounds were characterized by 1HNMR, MS, IR, and elemental analysis. Preliminary bioassays
通过引入各种氨基酸苄酯或氨基酸四氢呋喃-2-基,合成了两个系列的新型(Z)-乙炔吡喃类似物2a,2b,2c,2d,2e,2f,2g,2h,3a,3b,3c,3d。酯成乙炔吡喃并形成一个四氢嘧啶环以固定(Z)-构型。目标化合物的结构通过1 HNMR,MS,IR和元素分析进行表征。褐飞虱的初步生物测定指出所有乙炔吡喃类似物在100 mg / L时均表现出良好的杀虫活性,而化合物3b和3d提供了最佳的体外抑制活性,在20 mg / L时具有≥90%的死亡率。
