An N‐Linked Bidentate Phosphoramidite Ligand (N‐Me‐BIPAM) for Rhodium‐Catalyzed Asymmetric Addition of Arylboronic Acids to N‐Sulfonylarylaldimines

Abstract

AbstractA chiral N‐linked C2‐symmetric bidentate phosphoramidite (N‐Me‐BIPAM) was newly developed for the rhodium‐catalyzed enantioselective addition of arylboronic acids to N‐sulfonylimines. This ligand achieved high enantioselectivities in a range of 84–99% ee in additions of arylboronic acids to N‐tosyl‐ and N‐nosylarylaldimines.
