Uses
Uses in perfumery :
Damascenone-Beta® brings a fruity nuance for rosy notes. Gives a ''baked apple '' effect.
Year of discovery :
First rose ketones were discovered in 1965, by chemists P. Ruzicka and Dr. Demole, by analyzing Damask Rose Absolute. This opened the way to synthesize a major molecule category of the perfume industry.
Natural availability :
Damascenone-Beta® is present in small quantities in Damask Rose Absolute and Damask Rose EO (and other roses), from which it can be extracted. It is also present in Clary Sage Absolute and salvia officinale among others, always in very small proportions.
Isomerism :
There is an isomer of Damascenone-Beta® called Damascenone-Alpha®. Its smell is similar but the location of the double bonds in the ring is not the same (1,3 positions for beta and 2,4 positions for alpha). Cyclamen Aldehyde is a constitutional isomer of Damascenone-Beta, although its smell is completely different, as it is very marine, floral and aldehydic.
Synthesis precursor :
Damascenone-Beta® is not a precursor to the synthesis of another compound of olfactory interest.
Synthesis route :
Damascenone-Beta® is part of the ''rose ketones '' family, present in a small amount in Damask Rose Absolute, while playing an important role in their smell. Rose ketones are synthesized from the appropriate derivative of cyclogeranic acid (ester, halide, ...). A reaction of this derivative with an allyl magnesium halide followed by a pyrolysis, allows to obtain the desired compound by rearranging the double bond of the branched chain.
