Uses
Uses in perfumery :
Damascone-Beta® is used to give more facets to a fruity or rosy note. Gives an old apple facet. Often substituted by Verdox®, because this molecule is not restricted.
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-Beta® is present in very small quantities in Damask Rose Absolute (at 0.05%), from which it can be extracted. It is also present in the fragrant principle of some teas and tobaccos.
Isomerism :
In general, it is the racemic mixture of the two diastereomers of Damascone-Beta® that is used in perfumery. Both isomers of the molecule have a rather similar smell, but they can be used separately. 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-Beta® is not a precursor to the synthesis of another compound of olfactory interest.
Synthesis route :
Damascone-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. Pink 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.
