Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of central nervous system (CNS) agents. Its spirocyclic structure provides structural rigidity and stereochemical complexity, making it valuable in drug design for enhancing selectivity and metabolic stability. Commonly employed in research settings to build novel bioactive molecules, including potential antipsychotics and cognitive enhancers. Also explored in medicinal chemistry for its ability to mimic peptide-like frameworks, supporting the development of protease inhibitors and receptor modulators.
