A new approach for the enantioselective synthesis of various bicyclo[2.2.2]octadiene ligands has been developed, which features a chiral oxazaborolidinium-catalyzed asymmetric Diels-Alder reaction to construct bicyclo[2.2.2]octane framework. The pivotal ketone 12 served as common intermediate that was finally transformed into desired C1- and C2-symmetric dienes. This work provides an alternative method reported diene would be beneficial exploration potentials this type versatile ligand in transformations.
