Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of bioactive molecules targeting neurological and psychiatric disorders. Its structure allows for selective modification, making it valuable in medicinal chemistry for creating analogs with enhanced blood-brain barrier permeability. Commonly employed in the preparation of protease inhibitors and receptor modulators due to the stability and steric properties provided by the tert-butyl carbamate group. Also utilized in solid-phase synthesis and combinatorial chemistry for drug discovery.
