Used as a chiral building block in the synthesis of pharmaceuticals, particularly in the development of protease inhibitors and other bioactive molecules. Its rigid bicyclic structure and defined stereochemistry make it valuable for designing drugs with high selectivity and potency. Commonly employed in medicinal chemistry for structure-activity relationship (SAR) studies, especially in optimizing peptide-like compounds. The Boc-protected amine and carboxylic acid functionalities allow for straightforward incorporation into larger molecular frameworks through standard coupling reactions.
