Used as a chiral building block in the synthesis of biologically active molecules, particularly in the development of pharmaceuticals. Its protected amine and hydroxyl functionalities make it valuable in peptide-like structures and beta-amino alcohol synthesis. Commonly employed in asymmetric synthesis due to the stable chiral center, enabling selective formation of desired stereoisomers. The sulfonyl group enhances reactivity and directs selective transformations, useful in medicinal chemistry for constructing protease inhibitors or enzyme modulators.
