via a Wittig olefination reaction. The conver-gent syntheses of 1 consisted of a combination of two fragments, each containing an olefin with a fixed configuration, by formation of a third double bond to give a mixture of two geometric isomers. The mixtures of 1 were resolved by recycle high-performance liquid chromatography methods. 1H and 13C NMR peak assignments of the individual isomers were accomplished
通过Wittig烯化反应合成了3,6,8-十二碳三烯-1-醇1的八个几何异构体,即地下白蚁的尾随信息素(sp。Banks )。1的收敛合成由两个片段的组合组成,每个片段包含一个具有固定构型的烯烃,这是通过形成第三个双键给出的两种几何异构体的混合物。1的混合物通过循环高效液相色谱法分离。单个异构体的1 H和13 C NMR峰分配通过同核COSY和一键CH相关光谱法完成。
