Used as a key intermediate in the synthesis of pharmaceutical agents, particularly in the development of protease inhibitors and other biologically active molecules. Its structure supports the formation of chiral centers important for enantioselective drug design. Commonly employed in medicinal chemistry for constructing pyrrolidine-based scaffolds that enhance metabolic stability and binding affinity in drug candidates. Also utilized in asymmetric synthesis due to the presence of functional groups amenable to selective transformations.
