Iridium-Catalyzed Allylic Amination Route to α-Aminoboronates: Illustration of the Decisive Role of Boron Substituents.

A variety of α-amino trifluoroborates (III), (VIII) and (X) is prepared by Ir-catalyzed allylic amination of trifluoroborate-containing allylic carbonate (I) with secondary amines.
