Used in pharmaceutical synthesis as a chiral building block for the preparation of bioactive molecules, particularly in the development of protease inhibitors and peptide-based drugs. The iodine functionality allows for further cross-coupling reactions, such as Suzuki or Heck couplings, enabling structural diversification. The Boc-protected amine ensures selective deprotection and coupling in multi-step syntheses, while the methyl ester can be hydrolyzed to the corresponding carboxylic acid for amide bond formation. Commonly employed in the synthesis of enzyme inhibitors and targeted therapeutics where stereochemistry plays a critical role in biological activity.
