Used as a key intermediate in the synthesis of antidiabetic drugs, particularly in the production of DPP-4 inhibitors like vildagliptin and saxagliptin. Its chiral structure enables selective interaction with biological targets, enhancing drug efficacy and reducing side effects. Commonly employed in pharmaceutical research for developing oral hypoglycemic agents. Also utilized in asymmetric synthesis due to its stereochemical purity, supporting the development of enantiomerically pure therapeutics.
