Chemistry & Uses
Year of discovery :
1957
Natural availability :
Pino Acetaldehyde is not available in its natural state.
Isomerism :
Pino Acetaldehyde incudes two asymmetric carbons and one double bond, all included in a bicyclic group. This can only give birth to a unique isomeric form. Then, only one of the Pino Acetaldehyde isomers is used in perfumery. On another hand, Pino Acetaldehyde is a constitutional isomer of Phenoxanol®, even if it does not have the same smell at all.
Synthesis precursor :
Pino Acetaldehyde is not a precursor to the synthesis of another compound of olfactory interest.
Synthesis route :
The synthesis of Pino Acetaldehyde starts from alpha-Pinene. An epoxidation reaction between this molecule and peracetic acid gives birth to an intermediary called Pinocarveol, after a rearrangement of the epoxyde. An addition reaction between Pinocarveol and Ethyl Vinyl Ether forms another intermediary, able to undergo a Claisen rearrangement by being heated, giving birth to the final product, Pino Acetaldehyde.
Stability :
Aldehydes may form diethylacetals in alcoholic perfumes, with no real impact on their smell.
They also may form Schiff bases by reaction with Methyl Anthranilate or other nitrogen molecules such as Indol, among others.
Other comments :
While having a dominating marine note, Pino Acetaldehyde gets its name from a slight coniferous facet adding to its ozonic volume.
