An external chiral amidophosphine ligand for asymmetric conjugate addition of organocopper

Two types of external, chiral amidophosphine ligands, 1-5, were prepared. Examination of their behavior in an asymmetric conjugate addition reaction of organocuprate revealed the possibility for steric tuning to realize high selectivity.
