Uses
Uses in perfumery :
Damascone-Alpha® is used in rosy, tuberose, ambery and spicy notes. Gives a green, spicy and fruity facet to floral notes. Very effective, often used diluted.
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 :
Damascone-Alpha® is not available in its natural state.
Isomerism :
In most cases, it is the racemic mixture of the two diastereomers of Damascone-Alpha® that is used in perfumery. Both isomers of the molecule have a rather similar smell, but they can be used separately. The laevorotatory form of Damascone-Alpha® is more powerful than its dextroratatory form. Ionone alpha and beta are positional isomers of Damascone®, as their ketone function is on another carbon, as well as a methyl function, also relocated. Their smell is therefore very different: the Ionones are reminiscent of violet.
Synthesis precursor :
Damascone-Alpha® is not a precursor to the synthesis of another compound of olfactory interest.
Synthesis route :
Damascone-Alpha® 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.
