Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of bioactive molecules and central nervous system agents. Its spirocyclic structure and functional groups make it valuable for constructing complex heterocyclic compounds. Commonly employed in medicinal chemistry for building blocks in drug discovery, especially in the design of enzyme inhibitors and receptor modulators. The tert-butyl carbamate (Boc) group allows for easy protection of amines during multi-step syntheses, enhancing selectivity and yield in peptide-like and small-molecule drug development.
