component is essential. A new method is described for the stereospecific syntheses of six sex pheromone components 1 to 6 for the rice leaffolder moth. The crucial synthetic step for the compounds is the introduction of pure (Z)-double bond in the molecules. The starting material, cis-1,8-oct-4-en-diol (7) consisting of 100% (Z)configuration was stereospecifically prepared from readily available 1,5-cyclooctadiene
水稻卷叶蛾,Cnaphalocrocis medinalis,广泛分布于亚洲、大洋洲和非洲潮湿的热带至温带国家。是水稻重要的食叶害虫。据了解,在幼虫阶段,一个叶夹会消耗 6 到 7 片叶子。最近,它已在亚洲主要水稻种植区广泛传播,成为严重的害虫。合成的性信息素不仅可能是定时杀虫剂应用的有效监测工具,而且可能是一种控制剂。此前,两种化合物,(Z)-11-hexadecenyl acetate (1, Z11-16:Ac) 和 (Z)-13-octadecenyl acetate (6, Z13-18:Ac) 被鉴定为女性性信息素在印度和菲律宾进行的水稻卷叶蛾和田间试验(图 1)。另一方面,另外四种化合物,(Z)-11octadecen-1-ol (2, Z11-18:OH),(Z)-11-十八烯醛 (3, Z-1118:Ald)、(Z)-13-octadecen-1-ol (4, Z13-18:OH)
