Other names :
4-(Octahydro-4,7-methano-5Hinden-5-ylidene)butanal ; Muguet butanal ; 4-tricyclo(5.2.1.0 decylindene-8)butanal
Volatility :
Base
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.
Natural availability :
Dupical does not exist on a natural state. Thus, it can't be used as extracted from a plant.
Year of discovery :
1969
Other comments :

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