Used as a chiral building block in the synthesis of pharmaceutical intermediates, particularly in the preparation of protease inhibitors and other bioactive molecules. Its iodine functionality allows for further cross-coupling reactions, enabling the introduction of complex organic fragments. The Boc-protected amine ensures stability during reactions and can be selectively deprotected to release the amine for subsequent coupling steps. Commonly employed in peptide mimetic synthesis and in the development of labeled compounds for medicinal chemistry research.
