Used in the synthesis of chiral pharmaceuticals and asymmetric catalysts due to its enantiomerically pure structure. Commonly employed as a chiral building block in the preparation of protease inhibitors and other bioactive molecules. Also utilized in the development of chiral ligands for asymmetric hydrogenation reactions, enhancing stereoselectivity in organic synthesis. Its benzyl-protected amine group allows for selective deprotection and further functionalization in multi-step synthetic routes.
