es have been developed as efficient novel ligands for the rhodium‐catalyzed enantioselective 1,2‐addition of arylboronic acids to challenging aliphatic α‐ketoesters. By employing the linear or branched sulfinamide‐olefin ligands, interesting enantioselectivity as well as regioselectivity reversal in the related asymmetricadditions were observed.
