Used in pharmaceutical research as a key intermediate in the synthesis of biologically active compounds, particularly in the development of central nervous system agents. Its spirocyclic structure provides structural rigidity, making it valuable in medicinal chemistry for designing selective receptor ligands. Commonly employed in the preparation of cognitive enhancers and potential treatments for neurological disorders due to its ability to cross the blood-brain barrier. Also utilized in the optimization of drug candidates for improved metabolic stability and binding affinity.
