fluorine-containing Pinus diterpenic amides and imines have been synthesised and their structures were confirmed by elemental analysis, IR, 1H NMR spectroscopy and single crystal X-ray diffraction. Their insect attractant activity to Spodoptera litura were screened by leaf plate method; the results indicated that most fluorine-containing dehydroabietic amides and imines exhibited attractive activity to S. litura
合成了一系列的含氟松二萜酰胺和亚胺,并通过元素分析,IR,1 H NMR光谱和单晶X射线衍射确定了它们的结构。用叶板法筛选了其对斜纹夜蛾的昆虫引诱活性。结果表明,大多数含氟脱氢松香酰胺和亚胺都对斜纹夜蛾具有吸引力,其中在0.01 g mL -1浓度下,脱氢松香对三氟甲基酰胺(A6)的吸附率是空白品的七倍。。稠合到苯环的氟部分导致除(A6)以外的酰胺吸引率降低,而氟的作用导致二萜亚胺的吸引率提高。
