The development of a new route to alpha-aminoboronates using an iridium-catalyzedallylicamination on boronated substrates is described. Unlike the boronate group, the trifluoroborato substituent was found to govern the regioselectivity exclusively in favor of branched products. The transformation of an allylic substitution product into an alpha-aminoboronic ester in an efficient way validated the
