(11Z,13Z)-11,13-hexadecadienal, the female sex pheromone of the navel orangeworm (Amyelois transitella), was synthesized from commercially available 10-bromo-1-decanol in a 27% overall yield (8 steps). The synthesis was achieved by using 10-iododecanal, trimethylsilylacetylene and (Z)-1-bromo-1-butene as the key building blocks, employing Sonogashira-Hagihara coupling and Brown's hydroboration-protonolysis
(11Z,13Z)-11,13-十六碳二烯醛(脐橙蠕虫(Amyelois transitionella)的雌性信息素)由市售的10-溴-1-癸醇以27%的总产率合成(8步)。合成是通过使用10碘十二烷,三甲基甲硅烷基乙炔和(Z)-1-溴-1-丁烯作为主要结构单元,并以Sonogashira-Hagihara偶联和Brown的硼氢化-质子分解为关键反应。末端甲酰基在合成的较早阶段而不是最后一步中安装。该程序使这种具有重要经济意义的信息素能达到克级的制备。
