Used as a chiral building block in the synthesis of various pharmaceuticals, particularly in the development of antiviral and anticancer drugs. Its stereochemistry makes it valuable for creating enantiomerically pure compounds, which are crucial for drug efficacy and safety. Also employed in organic synthesis for constructing complex cyclic structures, aiding in the production of natural products and bioactive molecules. Its application extends to research and development in medicinal chemistry, where it serves as a key intermediate in designing molecules with specific biological activities.
