Application

3-Methyl-2-cyclohexenone is an insect sex pheromone of the Douglas-fir beetle. It can be used as a starting material:
  • In the total synthesis of (−)-ar-tenuifolene, a naturally occurring aromatic sesquiterpene.
  • To synthesize an organic building block 2-trimethylsilyl-3-methyl-cyclohexenone.
  • In the total synthesis of natural diterpenoids (+)-taiwaniaquinone H and (+)-dichroanone.
