double bonds is ≥95%. TheZ configuration of the Δ7 bond results from the 1,4-cis-hydrogenation of the intermediate 1,4,6-undecatrien-3-ol in the presence of an (arene)chromium tricarbonyl complex, while theE configuration of the Δ4 bond arises in the Claisen-Johnson rearrangement occuring in the reaction of 1,5Z-undecadien-3-ol with trimethyl orthoacetate.
从市售的 2,4-壬二烯醛开始,对标题化合物进行了简单的五步合成。信息素总收率为29%,Δ4和Δ7双键的几何纯度≥95%。Δ7 键的 Z 构型是由中间体 1,4,6-十一碳三烯-3-醇在(芳烃)三羰基铬配合物存在下的 1,4-顺式氢化产生的,而 Δ4 键的 E 构型产生在 1,5Z-undecadien-3-ol 与原乙酸三甲酯反应中发生的 Claisen-Johnson 重排。
