General description

(+)-Valencene is a sesquiterpene, which contains decalin framework and two methyl-bearing stereocenters. It is an aroma component of citrus fruit.

Application

(+)-Valencene can be used as a precursor to prepare:
  • (+)-Nootkatone (a sesquiterpene) by dark singlet oxygenation.
  • Benzoyloxyvalencene by reacting with tert-butyl peroxy benzoate via Kharasch−Sosnovsky allylic oxidation method.
  • (+)-Lineariifolianone, a natural product.
