Chemistry & Uses
Uses in perfumery :
Pharaone® is useful as a green booster from the top note, with a fruity effect.
Year of discovery :
1999
Natural availability :
Pharaone® does not exist on a natural state. Thus, it can't be used as extracted from a plant.
Isomerism :
Pharaone® is a constitutional isomer of Alpha-Ionone, Beta-Ionone, Alpha-Damascone® and Beta-Damascone®, but has a much fruitier smell, close to pineapple.
Synthesis precursor :
Pharaone® is not used for the synthesis of another molecule of olfactive interest.
Synthesis route :
The Pharaone® synthesis involves a few steps, starting from Cyclohexyl Acetaldehyde. The first step is a Mannich reaction involving formaldehyde in an acidic medium on the basic reagent, to add an alpha-positioned insaturated ramification, according to its cycle. The second step is a Grignard reaction, between the obtained intermediate product and an organomagnesian as butenylmagnesium bromide, to convert the aldehyde into an alcohol and add a carbon chain to the molecule. The last step is an oxydation that can be carried out using manganese oxide, converting the alcohol into a ketone. This step leads to Pharaone®.
Stability :
Stable in perfumes and in diverse functional bases, except in very acidic bases (detergents) and strong alkaline bases (liquid bleach).
Other comments :
Synergy with Stemone® in a 1:9 ratio of use, to create a tomato leaf effect.
