Used as a chiral building block in the synthesis of pharmaceutical intermediates, particularly in the development of protease inhibitors. Its rigid azasilolidine core provides stereochemical control in asymmetric synthesis, making it valuable in medicinal chemistry for constructing complex molecules with high enantiomeric purity. Commonly employed in peptide mimetics and drug discovery programs where steric hindrance and conformational stability are critical. The Boc-protected amine and carboxylic acid functionalities allow for straightforward incorporation into larger molecular architectures through standard coupling reactions.
