Used in pharmaceutical research as a key scaffold for developing bioactive molecules, particularly in central nervous system (CNS) drug discovery. Its spirocyclic structure offers high three-dimensional complexity and stereochemical stability, making it valuable for designing selective receptor modulators. Commonly explored in the development of antipsychotic, anxiolytic, and cognitive-enhancing agents due to its affinity for neurotransmitter receptors such as serotonin and dopamine receptors. Also investigated for its potential in improving metabolic stability and blood-brain barrier penetration in neuroactive compounds.
