Uses
Other comments :
Gamma-Damascone® is the most particular damascone. It has a confirous facet that makes it very different.
Stability :
Stable in perfumes and in various functional bases, except very alkaline bases as liquid bleach or some detergents.
Uses in perfumery :
Gamma-Damascone® can be used to make the link between a fruity and a coniferous note, to bring a cooked fruit effect. It also brings a dirty aspect to a composition, in association with aromatic notes.
Year of discovery :
First damascones were discovered in 1965 by chemists P. Ruzicka and Dr. Demole, by anayzing an extract as Damask Rose Absolute. This discovery showed the way to a new rosy and fruity molecule family.
Isomerism :
''Rose ketone '' family contains a few different molecules, almost all evoking cooked apple, blackcurrant and Damask Rose Absolute. Gamma-Damascone® has the most particular smell, with a coniferous facet, close to Thuyone, that makes its distinction. Beta-Damascone® and Alpha-Damascone® are both more rosy and minty. Alpha-Ionone and Beta-Ionone are both positional isomers of Damascone® molecules, because their ketone function is located on another carbon, and as they have a relocated methyl function. Nevertheless, their smell is very different, as Ionones are reminiscent of violet flower.
Synthesis precursor :
Gamma-Damascone® is not a precursor for the synthesis of another olfactive compound.
Natural availability :
Gamma-Damascone® is not found on a natural state. Thus, it is impossible to extract it in any way.
Synthesis route :
Gamma-Damascone® belongs to the ''rose-ketones '' family. Rose ketones are synthesized thanks to the appropriate cyclogeranic acid derivative (ester, halide…). Reacting this derivative with an allyl magnesium halide, followed by subsequent pyrolysis, leads to the desired compound, by rearranging the double bond of the branched chain.
