Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of beta-lactam antibiotics. Its structure allows for selective functionalization in multi-step organic reactions, making it valuable in constructing complex heterocyclic systems. Commonly employed in medicinal chemistry for modifying azetidine rings to enhance metabolic stability and bioavailability of drug candidates. Also utilized in the preparation of enzyme inhibitors and receptor modulators due to its ability to mimic peptide bonds while resisting degradation.
