Used as a key chiral building block in the synthesis of pharmaceuticals, particularly in the development of antiviral and central nervous system agents. Its rigid cyclopentane backbone with defined stereochemistry makes it valuable for designing enzyme inhibitors and receptor modulators. Commonly employed in medicinal chemistry for optimizing potency and selectivity in drug candidates. Also utilized in the preparation of peptidomimetics due to its structural similarity to natural amino acids while offering enhanced metabolic stability.
