Herein is reported the first example of palladium-catalyzed asymmetric allylic alkylation (AAA) reactions involving 2-aza-π-allyl palladium intermediates. The 2-aza-π-allyl complex was generated via a novel mode of activation of N-allyl imines. Pd-catalyzed C(sp³)–H activation of N-allyl imines and subsequent nucleophilic attack by glycinates delivered vicinal diamino derivatives as the sole regioisomers with high levels of diastereo- and enantio-control in the presence of the chiral, bidentate (S,S)-Cy-DIOP ligand. This procedure is highly atom economical and could also be performed by a simple one-pot operation starting from aldehydes, allyl amines and glycinates under mild conditions. The products of this transformation could be converted into various useful derivatives, where the allyl substitution serves as a unique tool for differentiating the two amino moieties in the products.

Pd催化的不对称烯丙位烷基化通过的C-H活化Ñ与甘氨酸烯丙基亚胺

本文报道了涉及2-氮杂-π-烯丙基钯中间体的钯催化的不对称烯丙基烷基化（AAA）反应的第一个例子。2-氮杂-π-烯丙基复合物是通过一种新的活化N-烯丙基亚胺的方式产生的。Pd催化N-烯丙基亚胺的C（sp ³）–H活化以及随后的甘氨酸盐的亲核攻击将邻二氨基氨基衍生物作为唯一的区域异构体，在手性，二齿存在的情况下具有非对映和对映体控制水平（S，S）-Cy-DIOP配体。该方法是高度原子经济的，并且还可以通过简单的一锅操作在温和的条件下从醛，烯丙基胺和甘氨酸盐开始进行。该转化的产物可以转化为各种有用的衍生物，其中烯丙基取代用作区分产物中两个氨基部分的独特工具。
