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 with alkyl vinyl ketones to give the corresponding adducts in good yields and high enantiomeric excesses under mild conditions.
