Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of chiral drugs where stereochemistry plays a critical role in biological activity. Its structure supports the construction of complex molecules with high enantioselectivity, making it valuable in asymmetric synthesis. Commonly employed in the preparation of active pharmaceutical ingredients (APIs) for central nervous system agents and protease inhibitors. The tert-butyl carbamate (Boc) group provides amine protection during peptide coupling and multi-step reactions, ensuring selective reactivity. Preferred in medicinal chemistry due to its stability under various reaction conditions and ease of deprotection when needed.
