Used as a chiral ligand in asymmetric catalysis, particularly in enantioselective organic transformations. Its rigid cycloheptane backbone and oxazoline rings provide a well-defined chiral environment, making it effective in coordinating to metal centers such as copper or palladium. This complexation enables high stereoselectivity in reactions like cyclopropanations, aldol additions, and allylic alkylations. The tert-butyl groups enhance steric shielding, improving enantiomeric excess in the products. Due to its stability and tunable geometry, it is employed in the synthesis of pharmaceuticals and fine chemicals where precise stereocontrol is required.
