Uses
Uses in perfumery :
Neofolione® is most often used in home care, detergents, fabric care and shampoos. Used in small quantities because of its power. Interesting for fruity notes and aldehydic floral notes for a fresh touch. Provides freshness and diffusion. Often used as a replacor of Methyl Octine Carbonate.
Year of discovery :
Data not available.
Natural availability :
Neofolione® is one of the compounds of the fragrant principle of artichoke. However, it cannot be extracted.
Isomerism :
Neofolione® has a double bond that offers the possibility of obtaining two diastereoisomers for this molecule. In perfumery, Neofolione® is a racemic mixture of these two isomers. The two isomers are not separated as they have no olfactory interest. In addition, Gamma-Decalactone and Linalool Oxide are constitutional isomers of Neofolione®. However, they have a very different smell.
Synthesis precursor :
Neofolione® is not a precursor to the synthesis of another compound of olfactory interest.
Synthesis route :
The synthesis of Neofolione® is made from Heptanal (Aldehyde C-7), condensed with malonic acid. This reaction is carried out in an acid medium. Then, follows a decarboxylation of the compound to remove the second acid function of the malonic acid, and a final step of esterification of the obtained molecule with methanol. This step requires an acid catalysis (with sulfuric acid for example) to improve the reaction yield.
