Used as an intermediate in the synthesis of pharmaceutical peptides, particularly in the preparation of protease inhibitors and other bioactive molecules. The presence of the iodophenyl group allows for further functionalization through cross-coupling reactions, such as Suzuki or Heck reactions, enabling the construction of complex aromatic side chains. The Cbz (benzyloxycarbonyl) protecting group facilitates selective amine protection during peptide assembly, while the stereochemistry supports the formation of chiral centers required for biological activity. Commonly employed in research settings for developing enzyme inhibitors and targeted therapeutics.
