Chemistry & Uses
Uses in perfumery :
Isocyclocitral® is used in chypre and fougere perfumes, in woody, carnation, geranium, honeysuckle and tomato leaf notes.
Year of discovery :
Data not available.
Natural availability :
Isocyclocitral® is not available in its natural state.
Isomerism :
Isocyclocitral® contains three asymmetric carbons that give various conformational possibilities. As the reagents used for its synthesis are mixtures of diastereoisomers, it is a mixture of isomers that is used in perfumery. Citral is a constitutional isomer of Isocyclocitral®. Nevertheless, its smell is much more hesperidated and less green.
Synthesis precursor :
Isocyclocitral® forms a Schiff base by reaction with Methyl Anthranilate. The resulting compound is quite woody and close to orange blossom.
Synthesis route :
The molecule of Isocyclocitral® can be synthesized by a Diels-Alder reaction between 2-butenal and 2-methylpenta-1,3-diene.
Stability :
Aldehydes may form diethylacetals in alcoholic perfumes, with no real impact on their smell.
Other comments :
Isocyclocitral® is much different from other cut grass smell as Triplal® because of its powerful mushroom identity.
