(4R,4′R,5S,5′S)-2,2′-(1-Methylethylidene) or (4S,5R)-Bis-Phbox) can be used as a ligand: To prepare selective exo-catalysts for enantioselective 1,3-dipolar cycloaddition reactions. In the asymmetric aminooxygenation of alkenes in the presence of tetramethylaminopyridyl radical (TEMPO) as an oxidant and copper(II) triflate as a catalyst. In asymmetric aminofluorination of olefins using an iron catalyst.
