Used as a key intermediate in the synthesis of antidiabetic drugs, particularly in the production of dipeptidyl peptidase-4 (DPP-4) inhibitors. Its chiral structure and functional groups enable selective binding and improved metabolic stability in active pharmaceutical ingredients. The compound’s fluorinated pyrrolidine core enhances bioavailability and resistance to enzymatic degradation, making it valuable in developing oral hypoglycemic agents. It is also employed in research for optimizing peptide mimetics due to its ability to mimic natural amino acid motifs while maintaining conformational rigidity.
