Orivone®

Other comments :

Orivone® is one of the key molecule reproducing the smell of orris root.

Stability :

Stable in perfumes and in diverse functional bases.

Uses in perfumery :

Orivone® is used in majority in orris root accords. It can also be used in nutty, dry woods and leather accords, to bring a dry effect and an orris root and powdery note in small quantity.

Year of discovery :

1950

Isomerism :

Orivone® is a constitutional isomer of Ethyl Linalool and so called Aldehyde C11 Lenic, but has no common facet with these two molecules.

Synthesis precursor :

Orivone® is not a precursor to the synthesis of any other molecule used in perfumery.

Natural availability :

Orivone® is not found in nature.

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.
