Used as a key chiral building block in the synthesis of pharmaceuticals, particularly in the development of protease inhibitors and other bioactive molecules. Its stereochemistry makes it valuable for constructing complex ring systems with high enantioselectivity. Commonly employed in medicinal chemistry for structure-activity relationship (SAR) studies due to the presence of multiple functional groups that allow for selective derivatization. Also utilized in the preparation of peptidomimetics and as an intermediate in the manufacture of drug candidates targeting viral infections and metabolic disorders.
