Synthesis and application of chiral bisphosphine ligands containing a hetero-functional group
摘要:
New chiral bisphosphine ligands bearing hetero-functional groups were prepared by the use of asymmetric Diels-Alder reaction and silver-ion catalyzed rearrangement as key steps. The bisphosphines, especially bearing a carboxyl group, were found to be efficient ligands for palladium-catalyzed asymmetric allylic alkylation.
