Application

2,6,6-Trimethyl-1-cyclohexene-1-acetaldehyde can be used as a starting material to prepare:
  • (±)-Aeginetolide by oxidation in the presence of meta-chloroperoxybenzoic acid (m-CPBA).
  • (±)-Dihydroactinidiolide (a C11-terpenic lactone) via dehydration of key intermediate aeginetolide.

It can also be used as a key intermediate to synthesize drimane-related sesquiterpenes and substituted retinoic acid analogs.
