Direct amination of benzylic C−H bonds generates important stereocenters. Our approach, in which the chirality of a bimetallic rhodium complex is located on its associated cations, achieves this on tertiary amide-containing substrates to give amination of arylbutyric and arylvaleric acid-derived amides. We believe that the amide most likely interacts directly with the chiral cation to provide a highly
苄基 C−H 键的直接胺化产生重要的立体中心。我们的方法中,双金属铑配合物的手性位于其相关的阳离子上,在含叔酰胺的底物上实现了这一点,得到芳基丁酸和芳基戊酸衍生的酰胺的胺化。我们认为酰胺很可能直接与手性阳离子相互作用,为 C−H 胺化提供高度有序的过渡态。
