Synthesis route :
One of the methods for synthesizing Cashmeran® is to oxidize pentamethyl tetrahydroindene in the presence of a cobalt naphthenate catalyst.
Synthesis precursor :
Cashmeran® is not a precursor to the synthesis of another compound of olfactory interest.
Isomerism :
Cashmeran® has an asymmetric carbon. It is nevertheless the racemic mixture of this molecule that is used in perfumery.
Alpha-Irone and Isoraldeine® are constitutional isomers of Cashmeran®. However, they have a violet and orris smell, different from Cashmeran®.
