Abstract

The defensive secretion of larvae of the chrysomelid beetle Plagiodera versicolora contains two unstable, volatile methylcyclopentanoid terpenes: a dialdehyde (chrysomelidial) isomeric with dolichodial and anisomorphal, and a closely related enol lactone (plagiolactone). Chrysomelidial and plagiolactone are shown to have structures III and IV on the basis of a detailed analysis of their spectra, coupled with chemical transformations to products of known structure.

摘要

叶甲科甲虫葡萄叶甲幼虫的防御性分泌物含有两种不稳定的挥发性甲基环戊烷类萜烯

一种二醛（葡萄叶甲醛），与长链二醛和异长链二醛同分异构，以及一种与之密切相关的烯醇内酯（葡萄叶甲内酯）。基于对它们光谱的详细分析，并结合化学转化为已知结构的产物，葡萄叶甲醛和葡萄叶甲内酯被证明具有结构III和IV。
