Used primarily in pharmaceutical research as a key intermediate in the synthesis of bioactive molecules, particularly those targeting central nervous system disorders. Its spirocyclic structure and functionalized side chain make it valuable for developing compounds with high receptor selectivity, especially in the design of potential antipsychotic and anticonvulsant agents. The hydroxyl group allows for further chemical modifications, enabling the creation of esters, ethers, or conjugates to improve pharmacokinetic properties such as solubility and blood-brain barrier penetration. Also explored in medicinal chemistry for structure-activity relationship (SAR) studies due to its rigid scaffold, which helps in conformational restriction of drug candidates.
