Used as a chiral building block in the synthesis of pharmaceuticals, particularly in the development of enzyme inhibitors and bioactive molecules. Its stereochemistry makes it valuable for creating specific enantiomers in drug candidates, especially in neurology and metabolic disease research. Commonly employed in the preparation of protease inhibitors and agents targeting central nervous system disorders. Also utilized in asymmetric synthesis due to the presence of two defined stereocenters, enabling high selectivity in complex molecule construction.
