Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of antiviral and central nervous system agents. Its rigid cyclopentane backbone with functional groups in close proximity makes it valuable for designing enzyme inhibitors and receptor modulators. Commonly employed in medicinal chemistry for structure-activity relationship studies due to its conformational restraint, enhancing selectivity and metabolic stability in drug candidates. Also utilized in the preparation of peptidomimetics and bioactive molecules where stereochemistry plays a critical role in biological activity.
