Other names :
Jasmalactone ; 6-(pent-3-en-1-yl)tetrahydro-2H-pyran-2-one ; Dec-8-eno-1,5-lactone ; 8-decen-5-olide ; Petal pyranone ; Tetrahydro-6-(3-pentenyl)-2H-pyran-2-one ; Tetrahydro-6-pent-3-enyl pyran-2-one
Volatility :
Base
Uses in perfumery :
Jasmolactone is used in luxury perfumery for reconstitutions of white flowers, for ambery notes and to give facets to a tea note.
Natural availability :
Jasmolactone is only present in trace amounts in Osmanthus Absolute, not allowing to obtain it in its natural state.
Year of discovery :
1961
Other comments :
Jasmolactone has a jasmine undernote that makes the difference with other lactones as Delta-Decalactone.
Price Range :
€€€€
Stability :
Lactones tend to polymerize through time, making them more viscous and leading to a phase shift in alcohol.

Synthesis route :
Like the other lactones, Jasmolactone, is synthesized by an intramolecular esterification reaction that involves 4-hydroxydec-8-enoic acid, in the presence of an acid catalyst. Then, the cyclization of this molecule gives rise to a δ-lactone.
Synthesis precursor :
Jasmolactone is not a precursor to the synthesis of another compound of olfactory interest.
Isomerism :
Another molecule is also called δ-Jasmolactone, but is synthesized from 4-hydroxydec-7-enoic acid, which places the double bond of the final product on another carbon aside. The smell of this isomer is similar to the Jasmolactone described here. Gamma-Jasmolactone has a more fatty smell, close to peanut.
Methyl Laitone® is a constitutional isomer of Jasmolactone, but has a coconut-like smell and a lactonic body.
