Used as an intermediate in organic synthesis, particularly in the preparation of pharmaceuticals and biologically active compounds. Its structure allows for selective modifications at the nitrogen and ester groups, making it valuable in the development of enzyme inhibitors and receptor ligands. Commonly employed in medicinal chemistry for constructing pyrrolidine-based scaffolds found in neuroactive drugs and cognitive enhancers. Also utilized in asymmetric synthesis due to its chiral centers, supporting the production of enantiomerically pure compounds.
