Used in pharmaceutical research as a key intermediate in the synthesis of neuroactive compounds, particularly those targeting central nervous system disorders. Its spirocyclic structure and functional groups make it valuable for developing drug candidates with enhanced selectivity and metabolic stability. Commonly employed in the preparation of serotonin and dopamine receptor modulators. Also utilized in the design of novel antidepressants and antipsychotic agents due to its favorable stereochemistry and ability to cross the blood-brain barrier.
