Chemistry & Uses

Uses in perfumery :

Lactone of cis-Jasmone is used mainly in fine fragrance in floral, fruity, sandalwood and vetiver notes. Very useful in heady floral notes.

Year of discovery :

Data not available.

Natural availability :

Lactone of cis-Jasmone is not available in its natural state.

Isomerism :

Lactone of cis-Jasmone has one asymmetric carbon. It is however a mixture of its two enantiomers that is used in perfumery.

Synthesis precursor :

Lactone of cis-Jasmone is not a precursor to the synthesis of another compound of olfactory interest.

Synthesis route :

Lactone of cis-Jasmone is synthesized by an intramolecular esterification reaction from 4-hydroxy-4-methyldec-7-enoic acid, in the presence of an acid catalyst such as concentrated sulfuric acid.

Stability :

Lactones tend to polymerize through time, making them more viscous and leading to a phase shift in alcohol.

Other comments :

Lactone cis-jasmone is named after its similar structure to cis-jasmone. Its structure differs by the position of the branch of the molecule ring, and by the presence of an ester function rather than a ketone function in its ring.
