Four isomers of 5, 7-dodecadien-1-ol were previously proposed as being the sex pheromone of the pine moth. The isomers were stereoselectively synthesized from 1-hexyne and tetrahydropyranyl ether of 5-hexyn-1-ol. The (5Z, 7Z)-isomer was synthesized by a Chodkiewic Cadiot reaction followed by hydroboration, and other three isomers by novel synthetic methods including the addition of zirconocene hydride [Schwarz's reagent (C5H5)2Zn(H)Cl] to control the regioselective coupling reaction. The 5, 8- and 5, 9-dodecadien-1-ols were also synthesized by similar methods for comparison of their characteristics with the endogenous sex pheromone.
过去曾提出5,7-十二碳二烯-1-醇的4种异构体为松树蚕的性信息素。这些异构体是通过对1-己炔和5-己炔-1-醇的四氢吡喃醚进行立体选择性合成得到的。(5Z, 7Z)异构体是通过Chodkiewic Cadiot反应和随后的硼氢化反应合成的,而其他三种异构体则是通过包括使用二茂锆氢化物[Schwarz试剂(C5H5)2Zn(H)Cl]调控区域选择性偶联反应的新颖合成方法获得的。5,8-和5,9-十二碳二烯-1-醇也通过类似方法合成,以便与内源性性信息素的特性进行比较。
