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 and nitrogen-containing rings make it valuable for designing molecules with specific stereochemistry and receptor selectivity. Commonly employed in medicinal chemistry for constructing novel drug candidates targeting neurological disorders and psychiatric conditions. Also utilized in the preparation of kinase inhibitors and other enzyme modulators due to its ability to mimic peptide-like frameworks.
