Used as a chiral building block in the synthesis of pharmaceuticals, particularly in the development of peptide-based drugs and enzyme inhibitors. Its alkyne functionality allows for further modification via click chemistry, enabling efficient conjugation in drug discovery and bioconjugation applications. The Boc-protected amine group provides stability during synthesis and can be selectively deprotected to form amide bonds. Commonly employed in research settings for the preparation of structurally complex bioactive molecules.
