Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of bioactive molecules with central nervous system activity. Its protected azetidine structure 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 the preparation of enzyme inhibitors and receptor modulators, especially in programs targeting neurological disorders and inflammation. The hydroxyl and carboxylate groups enable further derivatization, supporting its role in building complex drug-like molecules.
