Used as a chiral building block in the synthesis of pharmaceuticals, particularly in the development of active pharmaceutical ingredients (APIs) requiring high enantiomeric purity. Its structure supports the formation of complex nitrogen-containing heterocycles, making it valuable in medicinal chemistry for drug discovery. Commonly employed in the preparation of protease inhibitors and other bioactive molecules where stereochemistry plays a critical role in biological activity. Also utilized in asymmetric synthesis to introduce chirality in target molecules.
