Used as a chiral building block in the synthesis of pharmaceuticals, particularly in the development of enzyme inhibitors and bioactive molecules. Its protected azetidine core allows for selective functionalization, making it valuable in medicinal chemistry for constructing constrained ring systems that enhance metabolic stability and binding affinity. Commonly employed in asymmetric synthesis due to the stereochemical control it offers at the 2-position. Also utilized in the preparation of peptidomimetics and as an intermediate in the production of beta-lactamase inhibitors.
