Dolichodial is a natural chemical compound with two aldehyde groups, which belongs to the group of iridoids.
Chemistry
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.
- (1R,2S,5S) = (−)-Dolichodial (A)
- (1S,2S,5S) = (+)-Anisomorphal (B)
- (1S,2S,5R) = Peruphasmal (C)
- (1S,2S,5R) = D
- (1S,2R,5R) = (+)-Dolichodial (A’)
- (1R,2R,5R) = (−)-Anisomorphal (B’)
- (1S,2R,5S) = Peruphasmal (C’)
- (1R,2R,5S) = D’
Occurrence
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]
