Chrysomelidial is a monocyclic mono terpene with two aldehyde groups , which belongs to the group of iridoids .
Chrysomelidial has two asymmetric carbon atoms and therefore occurs in two diastereomeric pairs of enantiomers . Chrysomelidial and a diastereomer (Epi-Chrysomelidial) can be found in the defensive secretions of some types of beetles and mites . It gets its name from the leaf beetles (Chrysomelidae). The two enantiomers, which are mirror images of the chrysomelidial and the epi-chrysomelidial, have so far only been known from plants, for example from the Japanese ray pen , and are usually referred to as (+) - and (-) - dehydroiridodial.
