Used as a chiral auxiliary or ligand in asymmetric synthesis, particularly in enantioselective catalysis. Its rigid oxazole framework and stereogenic center make it effective in controlling stereochemistry during carbon-carbon bond-forming reactions. Commonly employed in transition metal-catalyzed reactions such as aldol, Diels-Alder, and Heck reactions to achieve high enantiomeric excess. Also utilized in the development of pharmaceutical intermediates where precise stereocontrol is required. Its benzo[b]thiophene moiety enhances stability and can influence binding affinity in catalytic systems.
