Used as a chiral auxiliary and asymmetric synthesis building block in pharmaceutical research. Its rigid polycyclic structure supports stereocontrol during key bond-forming reactions, especially in enantioselective catalysis. Commonly employed in the development of optically active compounds, including bioactive molecules and natural product analogs. Its oxazole-indene framework enhances stability and selectivity in transition metal-catalyzed transformations. Also applied in materials science for designing chiral ligands and asymmetric catalysts.
