Used as a chiral building block in the synthesis of biologically active compounds, particularly in pharmaceutical development. Its iodine functionality allows for further cross-coupling reactions, such as Suzuki or Stille couplings, enabling the introduction of aromatic or heteroaromatic groups. The Boc-protected amine provides stability and controlled deprotection during peptide synthesis or in multistep sequences. The ester group can be hydrolyzed to the corresponding carboxylic acid or reduced to an alcohol, offering versatility in molecular design. Commonly employed in the preparation of enzyme inhibitors and peptidomimetics where stereochemistry plays a critical role in activity.
