Chemistry & Uses
Uses in perfumery :
Cis-jasmone is used in floral notes (tuberose, jasmine, gardenia) and ambery notes. Supports Hedione® and brings depth and power to jasmine notes.
Year of discovery :
Data not available.
Natural availability :
Cis-jasmone is found in Grandiflorum Jasmine Absolute (and other origins), Daffodil Absolute and Champaca Absolute. It can be extracted in its natural state from Grandiflorum Jasmine Absolute.
Isomerism :
The double bond guiding this cis-Jasmone conformation could also give rise to a trans conformation, depending on the synthesis conditions. The resulting smell would be much more earthy and close to mushroom.
Synthesis precursor :
Cis-jasmone is not a precursor to the synthesis of another compound of olfactory interest.
Synthesis route :
A synthetic route of cis-Jasmone consists of a nucleophilic substitution reaction between 3-methyl-2-cyclopenten-1-one and cis-2-pentenyl chloride, in the presence of sodium hydroxide.
Stability :
Unstable in acidic products, except fabric conditioners, and in very alkaline detergents.
Other comments :
Dihydrojasmone has a slightlymore almond and less green smell than cis-Jasmone.
