Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of protease inhibitors and other biologically active molecules. Its structure allows for selective functionalization, making it valuable in medicinal chemistry for building complex heterocyclic systems. Commonly employed in peptide mimetic design due to the presence of a carbonyl group and carboxylic acid functionality, enabling amide bond formation. Also utilized in solid-phase and solution-phase organic synthesis for constructing pyrrolidine-based scaffolds found in drug candidates.
