Synthesis route :
Parmavert® can be synthesized by an acetalization reaction of nonynaldehyde (nonynal). This reaction puts the aldehyde in the presence of an acid catalyst followed by methanol. This stage leads to the formation of a hemiacetal. The second step is a nucleophilic addition. In an acidic medium, a new methanol molecule can be added to the intermediate molecule to form Parmavert®.
The equilibrium of those two reactions can be shifted by using a Dean-Stark separator.
Synthesis precursor :
Parmavert® is not a precursor to the synthesis of another compound of olfactory interest.
Isomerism :
Parmavert® is a constitutional isomer of aldehyde C-14 and Citronellyl Formate. However, its smell is quite different from the latter two compounds.
