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.

Sesquiterpenoids are important secondary metabolites with various pharma- and nutraceutical properties. In particular, higher basidiomycetes possess a versatile biosynthetic repertoire for these bioactive compounds. To date, only a few microbial production systems for fungal sesquiterpenoids have been established. Here, we
