Used as a chiral auxiliary or ligand in asymmetric synthesis, particularly in enantioselective catalysis. Its rigid oxazole framework and stereogenic centers make it effective in controlling stereochemistry during carbon-carbon bond-forming reactions. Commonly employed in asymmetric aldol, Diels-Alder, and Michael addition reactions to achieve high enantiomeric excess. The sulfinyl group enhances coordination with metal centers, enabling efficient chiral induction when used in metal-catalyzed transformations. Also applied in the synthesis of pharmaceutical intermediates where precise stereocontrol is required.
