Description
Summary:The complex of [Rh(COD)Cl] 2 and ( R , R )-BDPP was used as an effective catalyst for the asymmetric ring opening reaction of oxabenzonorbornadienes with various amines by employing ZnI 2 as the activator. Under the optimized reaction conditions, high enantioselectivities with good yields could be obtained from a wide scope of oxabenzonorbornadienes and amines. The asymmetric ring opening reactions of oxabenzonorbornadienes with various amines were developed in high enantioselectivities with good yields by using a rhodium catalyst and ZnI 2 as the activator.
