以α -蒎烯为原料 ,控制反应条件 ,用不同氧化剂进行选择性区域氧化 ,合成了松小蠹信息素马鞭烯醇 (Ⅰ )、马鞭烯酮 (Ⅱ )、桃金娘烯醇 (Ⅲ )和桃金娘烯醛 (Ⅳ ) ,并用IR和MS谱验证了结构 .用化合物 (Ⅰ～Ⅳ )对纵坑切梢小蠹进行生物活性测定 ,结果表明 ,它们对纵坑切梢小蠹均有一定聚集作用 ,当用α -蒎烯配制成复方时 ,其诱集率提高 ,特别是纵坑切梢小蠹梢转干期的诱集率明显高于梢转梢期 Using α - pinene as raw material, the reaction conditions were controlled and oxidized with different oxidants to synthesize the pinopirin (Ⅰ), whirlerone (Ⅱ) and myrtenol (Ⅲ) And myrtenal (Ⅳ), and their structures were confirmed by IR and MS spectra. The biological activities of the compounds (Ⅰ ~ Ⅳ) A certain aggregation effect, when formulated with α - pinene compound, the trap rate increased, especially in the vertical pit tip of the small beetle turn dry period of the trap rate was significantly higher than the shoot tip shoot period
