Used as a chiral building block in asymmetric synthesis, particularly in the pharmaceutical industry for the production of enantiomerically pure drugs. Its stereochemistry makes it valuable in catalyzing or directing stereoselective reactions, such as aldol condensations or alkylations. Commonly employed in the development of chiral ligands and auxiliaries for transition metal-catalyzed reactions. Also utilized in the synthesis of bioactive molecules, including antiviral and anticancer agents, where precise stereochemistry is critical for biological activity.
