Chemistry & Uses

Year of discovery :

1969

Natural availability :

Dupical does not exist on a natural state. Thus, it can't be used as extracted from a plant.

Isomerism :

Dupical contains a few asymmetric carbons and a double bond, giving birth to many possible isomers. Nevertheless, a blend of these isomers is used in perfumery.

Synthesis precursor :

Dupical is not used for the synthesis of another molecule of olfactive interest.

Synthesis route :

Dupical can be synthesized starting from tricyclododecanone, by reacting it with a Grignard reagent called vinylmagnesium bromide, to form and alcoholic intermediate with a vinylic group. A Claisen rearrangement can then be carried out by heating the intermediary product, converting it into Dupical.

Stability :

Very unstable in stong acidic (detergents) and alkaline (liquid bleach) bases. Only stable in shampoo, candle and soap bases.

Other comments :

Synergy with Methyl Laitone, to give a lactonic effect to a floral or fruity note.
