Used as a chiral building block in the synthesis of pharmaceuticals, particularly in the development of bioactive molecules where stereochemistry plays a critical role. Its hydroxyl and carbamate functional groups allow for selective modifications, making it valuable in the preparation of protease inhibitors, kinase inhibitors, and other therapeutic agents. Commonly employed in asymmetric synthesis to introduce chirality in drug candidates, especially in the design of central nervous system agents and antiviral compounds. The tert-butyl carbamate group also serves as a protected amine, enabling controlled deprotection during multi-step syntheses.
