Used as a key chiral intermediate in the synthesis of angiotensin II receptor antagonists, particularly in the production of antihypertensive drugs like valsartan and related sartan-class medications. Its stereochemistry enables selective binding and improved pharmacokinetic properties in the final drug substance. The Boc-protected amine and carboxylic acid functional groups allow for stepwise peptide-like coupling and deprotection strategies in multi-step organic synthesis. Commonly employed in pharmaceutical research and development for building complex molecules requiring high enantiomeric purity.
