General description

(+)-nootkatone, a bicyclic conjugated sesquiterpene ketone with a grapefruit-like flavor, is commonly used in fragrance, food, cosmetics and pharmaceutical industry. It can be synthesized from (+)-valencene via biotransformation. (+)-nootkatone is the active ingredient responsible for the antiplatelet effect of Cyperus rotundus, a well-known oriental traditional medicine. It also shows promising efficacy against Staphylococcus aureus biofilms.

Application

(+)-Nootkatone can be used:
  • In the iron(III) porphyrin catalyzed alkene aziridination reaction with organic azides under photo-irradiation condition.
  • As a substrate to synthesize its corresponding triene derivative through reduction-elimination reaction using iridium catalyst.
