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®.
Synthesis precursor :
Pharaone® is not used for the synthesis of another molecule of olfactive interest.
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.
