Application

This compound serves as a key intermediate in the synthesis of prostaglandin analogs and other bioactive cyclopentanoids. Its α,β-unsaturated ketone moiety enables Michael addition reactions, while the allyl group participates in cross-coupling and cyclization strategies. Researchers utilize it for developing novel flavor compounds due to its structural similarity to raspberry ketone derivatives. The hydroxyl group further allows for selective functionalization in polymer precursor synthesis.
