Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of CNS-active agents. Its spirocyclic structure and functional groups make it valuable for constructing complex heterocyclic systems found in experimental drugs targeting neurological disorders. The tert-butyl carbamate (Boc) group allows for selective protection during peptide-like coupling reactions, enabling controlled stepwise synthesis. It is also employed in medicinal chemistry research to explore structure-activity relationships in novel piperidine- and pyrazole-based derivatives.
