The enantiomers of O,N-bis(diphenylphosphino)-2-exo-hydroxy,3-endo-methylamino-norbornene have been prepared from the corresponding aminoalcohols and Ph2PCl.These compounds have been used as ligand for Rh complexes and tested in asymmetric hydrogenation of α-acetamidocinnamic acid, methyl-α-acetamidocinnamate and acetamodoacrylic acid.Optical yields of up to 90percent were obtained.
