Synthesis route :
Orivone® can be synthesized in one step from 4-tert-amylphenol, by a selective hydrogenation reaction, catalyzed by a heterogeneous catalysor such as palladium on alumina. 4-tert-amylphenol can be taken as a starting reagent, but it can also be synthesized first by an selective alkylation reaction from phenol, on a para position, reacting with amyl chloride, with a Lewis acid catalysor.
Synthesis precursor :
Orivone® is not a precursor to the synthesis of any other molecule used in perfumery.
Isomerism :
Orivone® is a constitutional isomer of Ethyl Linalool and so called Aldehyde C11 Lenic, but has no common facet with these two molecules.
