Chemistry & Uses

Uses in perfumery :

Dihydrojasmone is sometimes used to replace cis-Jasmone, as it is less costly, is jasmine accords to bring deepness.

Year of discovery :

Data not available.

Natural availability :

Dihydrojasmone is a purely synthetic molecule, not found on its natrual state.

Isomerism :

Having a double bond in its cycle, Dihydrojasmone is isomericly pure.

Synthesis precursor :

Dihydrojasmone is not used for the synthesis of another compound used in perfumery.

Synthesis route :

Dihydrojasmone can be prepared in several ways. One of them is an intramolecular aldolic condensation of 2,5-undecanedione. This molecule is prepared by reacting heptanal with 3-buten-2-one, in the presence of a thiazolium salt. The aldol condensation simply consists in mixing the dione with a strong acid.

Stability :

Unstable in acidic products, except fabric conditioners, and in very alkaline detergents.

Other comments :

Comparing it with cis-Jasmone, Dihydrojasmone has a more almond and less green smell than its homologue.
