circles: Leaf‐beetlelarvae synthesise the iridoid monoterpene chrysomelidial as a defensive compound. Feeding experiments with the deuterated precursor [2H5]8‐hydroxygeraniol indicated twostereodivergentcyclisationmodes towards chrysomelidial. To study the influence of the cyclisationmode on the stereochemistry, the configurations of chrysomelidials from seven species of leaf‐beetlelarvae were determined
