Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of biologically active molecules targeting central nervous system disorders. Its protected amine functionality allows for selective reactions in multi-step organic syntheses, making it valuable in medicinal chemistry. The cyclobutyl scaffold contributes to metabolic stability and improved binding affinity in drug candidates. Commonly employed in the preparation of protease inhibitors and receptor modulators where structural rigidity enhances potency and selectivity.
