Used as an intermediate in pharmaceutical synthesis, particularly in the development of bioactive molecules and drug candidates. Its spirocyclic structure and functional groups make it valuable for constructing complex heterocyclic compounds. Commonly employed in medicinal chemistry for designing protease inhibitors and kinase inhibitors. Also utilized in the preparation of novel compounds for research in central nervous system disorders due to its structural similarity to certain neuroactive scaffolds. The tert-butyl carbamate (Boc) group allows for easy protection and deprotection during multi-step syntheses, enhancing its utility in peptide-like and small-molecule drug development.
