Used as a key chiral intermediate in the synthesis of pharmaceuticals, particularly in the production of antiviral drugs. Its stereochemistry enables selective reactions critical for active pharmaceutical ingredient (API) development. Commonly employed in the manufacture of diabetes medications, including certain DPP-4 inhibitors, where it contributes to the molecule's ability to bind specifically to target enzymes. The protected alcohol and amine groups allow for stepwise functionalization during multi-step synthesis, making it valuable in industrial-scale drug production.
