Dolichodial is a natural chemical compound with two aldehyde groups, which belongs to the group of iridoids.
Chemistry
[edit]It has in its five-membered ring three asymmetric carbon atoms and accordingly exists in four diastereomeric pairs of enantiomers. The pairs with a different stereochemistry of dolichodial are called anisomorphal and peruphasmal.

Occurrence
[edit]Dolichodial and its stereoisomers can be found in the essential oils of certain plants, and also in the defensive secretions of some insect species.[1][2][3]
