Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of beta-lactam antibiotics and other bioactive molecules. Its structure supports the construction of complex heterocyclic systems found in drug candidates. Commonly employed in medicinal chemistry for modifying azetidine-containing scaffolds to enhance metabolic stability and binding affinity. Also utilized in the preparation of protease inhibitors and kinase inhibitors due to its ability to mimic amino acid motifs in peptide-like structures.
