The development of a new route to alpha-aminoboronates using an iridium-catalyzed allylic amination 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
描述了在硼化底物上使用铱催化烯丙基胺化制备 α-氨基硼酸盐的新途径的开发。与硼酸酯基团不同,发现三氟硼酸根取代基仅控制区域选择性,有利于支化产物。烯丙基取代产物以有效方式转化为α-氨基硼酸酯验证了该方法的实施。
