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 synthetic processes and can be selectively deprotected to allow for peptide coupling. Commonly employed in research settings for the preparation of structurally complex bioactive molecules.
