Used as an intermediate in pharmaceutical synthesis, particularly in the development of bioactive molecules and drug candidates. Its structure supports the construction of complex organic compounds, especially those requiring functionalized azetidine rings. The ester and tert-butyl carbamate (Boc) groups allow for selective reactions and protection strategies in multi-step syntheses. Commonly employed in medicinal chemistry for designing protease inhibitors, receptor modulators, and other therapeutic agents where small ring systems enhance metabolic stability and binding affinity.
