Preparation and application of a polymer-supported chiral π-allylpalladium catalyst for the allylation of imines

The polymer-supported chiral π-allylpalladium catalyst 8 was applied to the asymmetric allylation reaction of imines 9 with allyltributylstannane. The catalyst was very stable and could be reused several times with high catalytic activity, although the enantioselectivity was not necessarily high.
