Other names :
3,7,10-humulatriene ; α-caryophyllène ; (1E,4E,8E)-2,6,6,9-tétraméthylcycloundéca-1,4,8-triène
Volatility :
Base
Uses in perfumery :
Rarely used as such. Humulene-alpha is however very present in our formulas because it is a component of a large number of essential oils. It is therefore very commun to find it in the results of chromatographic analysis.
Natural availability :
This molecule is found in a countless number of essential oils, usually in trace amounts. Among the essential oils concerned, we find the great majority of spices, herbs, woods and citrus.
Year of discovery :
First isolated from hops, hence the name

Synthesis route :
Alpha-humulene is a sesquiterpene. This means that it has three units of Isoprenes. Isoprene is a five carbon atoms diene, constituting a basis for the synthesis of terpenes by Diels-Alder reactions. Thus, humulene can be synthesized from isoprene, or other easily obtainable terpenes, to shorten the synthesis.
