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.
Synthesis precursor :
Dihydrojasmone is not used for the synthesis of another compound used in perfumery.
Isomerism :
Having a double bond in its cycle, Dihydrojasmone is isomericly pure.
