Floralozone®

Other comments :

Floralozone® has a distinctive anisic note, making the difference with other ozonic notes as Cyclamen Aldehyde®.

Stability :

Aldehydes may form diethylacetals in alcoholic perfumes, with no significant impact on their smell. They also are able to react with molecules containing nitrogen as Methyl Anthranilate or Indol to form Schiff bases.

Uses in perfumery :

Floralozone® is used to make the link between a marine note and a floral note. It also enters in lilac accords, and brings a rubbery effect if overdosed.

Year of discovery :

Data not available.

Isomerism :

Floralozone® consists of two positional isomers: ortho and para. These two isomers are formed during the synthesis of Floralozone®, and are not used separately. Floralozone® is also a positional isomer of Cyclamen Aldehyde. Both have a marine and floral note, but differ in an aniseed character for Floralozone®, and a more aldehydic note for Cyclamen Aldehyde.

Synthesis precursor :

Floralozone® is not a precursor for the synthesis of another compound of olfactive interest.

Natural availability :

Floralozone® is not found in nature, and can therefor not be extracted.

Synthesis route :

Floralozone® can be synthesized in two steps from benzene. The first step is a Friedel and Craft alkylation reaction. This reaction uses for example chloroethane, reacting with a Lewis acid such as aluminium chloride. By adding benzene under pressure, it is possible to obtain ethylbenzene. In the second step, 4-chloro-2,2-dimethylpropanal is reacted in the same way with the intermediate product formed, after reacting with the same Lewis acid. The two isomers obtained are then the ortho and para isomers of ethyl 2,2-dimethylbenzenepropanal.
