Used as a key chiral intermediate in the synthesis of pharmaceuticals, particularly in the production of antidiabetic drugs such as DPP-4 inhibitors. Its stereochemistry allows for selective interactions in biological systems, enhancing drug efficacy and reducing side effects. Commonly employed in asymmetric synthesis to introduce specific functional groups with high enantiomeric purity. Also utilized in the development of protease inhibitors and other bioactive molecules requiring precise 3D structural control.
