Dupical

Other comments :

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

Stability :

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

Uses in perfumery :

Dupical is generally used in floral notes as lily of the valley or hyacinth. It brings freshness and an interesting aquatic note. It is very strong. It has to be used in small quantities.

Year of discovery :

1969

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.

Natural availability :

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

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.
