Used as a key intermediate in the synthesis of pharmaceutical agents, particularly in the development of neuroactive compounds and central nervous system modulators. Its spirocyclic structure and nitrogen-containing ring make it valuable for designing drugs with enhanced selectivity and bioavailability, including the ability to cross the blood-brain barrier for direct action in the brain. Commonly employed in medicinal chemistry for optimizing receptor binding, especially in targets related to psychiatric and neurological disorders, such as antidepressants and mood stabilizers. Also utilized in the preparation of enzyme inhibitors due to its rigid framework and functional handle for further derivatization.
