| Abstract: | The bifunctional chiral phosphine Lewis base (R)-2'-diphenylphosphino-1,1'-binaphthalene]-2-ol is an effective organocatalyst in the asymmetric aza-MBH reaction of ethyl (arylimino)acetates 1 with MVK and EVK to give the corresponding adducts in moderate to good yields and good to high enantiomeric excesses under mild conditions. |
