Used as a key chiral intermediate in the synthesis of pharmaceutical agents, particularly in the development of protease inhibitors and other bioactive molecules. Its strained azetidine ring and defined stereochemistry make it valuable for constructing conformationally restricted scaffolds in drug design. Commonly employed in medicinal chemistry to improve metabolic stability and binding selectivity. Also utilized in the preparation of enzyme inhibitors where the hydroxy and carbamate functionalities allow for further chemical modifications.
