Used as a key intermediate in the synthesis of pharmaceuticals and bioactive molecules, particularly in the development of protease inhibitors and peptide mimetics. Its hydroxyl and protected amine functional groups allow selective reactions, making it valuable in solid-phase and solution-phase organic synthesis. Commonly employed in the preparation of drug candidates where controlled functional group manipulation is required. Also utilized in the construction of complex heterocyclic systems through cyclization reactions. Its Boc-protected amine ensures stability during multi-step syntheses, enabling high yields and purity in final products.
