Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of bioactive molecules with central nervous system activity. Its spirocyclic structure and chiral center make it valuable in medicinal chemistry for designing potent and selective drug candidates. Commonly employed in the preparation of enzyme inhibitors and receptor modulators, especially in research targeting neurological disorders. The tert-butyl carbamate (Boc) group allows for easy protection of amines during peptide-like synthesis, enabling stepwise construction of complex molecules. Its stability under various reaction conditions supports use in multi-step organic syntheses.
