Description

  • Application: (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.[1] In the asymmetric aminooxygenation of alkenes in the presence of tetramethylaminopyridyl radical (TEMPO) as an oxidant and copper(II) triflate as a catalyst.[2]In asymmetric aminofluorination of olefins using an iron catalyst.[3]This chiral Box ligand was most recently shown to mediate an asymmetric aminofluorination of olefins utlizing Xtalfuor-E (719439) and TREAT-HF (344648). The resulting cyclic carbamates can be readily converted into their concomitant beta-fluoro amino acids.
  • Other Notes: Iron(II)-Catalyzed Intramolecular Olefin Aminofluorination
