Used as a chiral building block in the synthesis of pharmaceuticals, particularly in the production of β-amino alcohols and peptidomimetic compounds. Its hydroxyl and protected amino groups allow for selective functionalization, making it valuable in asymmetric synthesis and drug development. Commonly employed in the preparation of protease inhibitors and other bioactive molecules where stereochemistry is critical. The Boc-protected amine ensures stability during reactions and can be deprotected under mild acidic conditions, enabling further coupling steps in multi-step syntheses.
