Used as a chiral building block in the synthesis of pharmaceuticals, particularly in the development of protease inhibitors and other biologically active molecules. Its stereochemistry makes it valuable for constructing peptide-like structures with high enantioselectivity. Commonly employed in medicinal chemistry for drug discovery, especially in the preparation of intermediates for antihypertensive agents and enzyme inhibitors. The Boc-protected amine allows for controlled deprotection and coupling in multi-step syntheses, making it ideal for solid-phase and solution-phase peptide synthesis.
