Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of central nervous system (CNS) agents. Its spirocyclic structure and functional groups make it valuable in medicinal chemistry for designing compounds with improved metabolic stability and receptor selectivity. Commonly employed in the preparation of cognitive enhancers and neuroprotective agents. Also utilized in research settings for structure-activity relationship (SAR) studies due to its rigid framework, which helps in conformational restriction of biologically active molecules.
