Regioselective Synthesis of Optically Active Trifluoromethyl Group Substituted Allylic Amines by Palladium-Catalyzed Allylic Amination

We succeeded in the regioselective synthesis of chiral trifluoromethyl group substituted allylic amines from chiral allyl acetate using two types of palladium catalysts. Furthermore, we found that the kinetic resolution had occurred during the isomerization step from the gamma-type product to the alpha-type product by the [Pd(C3H5)(cod)]BF4/(S)-BINAP catalyst.
