Uses
Uses in perfumery :
Pino Acetaldehyde gives a green facet to some fruity notes such as pineapple, and gives a ''shiny '' effect in every kind of perfumes.
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.
