Used in peptide synthesis and medicinal chemistry as a chiral building block for the preparation of complex organic molecules. Its protected functional groups allow selective deprotection and coupling, making it valuable in the development of pharmaceuticals, particularly in the synthesis of protease inhibitors and other bioactive compounds. Commonly employed in solid-phase peptide synthesis due to compatibility with Fmoc-strategy. The Boc and Fmoc groups provide orthogonal protection, enabling precise control over amine reactivity during multi-step syntheses.
