Herein, we developed an Ir/phase‐transfer‐catalysis cooperatively catalyzed asymmetric cascade allylation/2‐aza‐Cope rearrangement of aldimine esters to prepare synthetically important homoallylic amines in good yields with excellent enantioselectivities. Compared with the bimetallic catalytic system to realize this transformation, the current cooperative Ir/tetrabutyl ammonium bromide catalytic system provides an alternative but more practical approach, which not only simplify the manipulation process but also increase the cost efficiency.

Ir /相转移催化协同催化不对称级联烯丙基化/ 2-氮杂-对位重排：从醛亚胺酯制取均烯丙基胺的有效途径†

本文中，我们开发了Ir /相转移催化协同催化的亚胺基酯的不对称级联烯丙基化/ 2-氮杂-Cope重排反应，以高收率和出色的对映选择性制备了重要的合成均胺。与实现这种转化的双金属催化体系相比，目前的协同铱/四丁基溴化铵催化体系提供了一种替代方法，但更加实用，不仅简化了操作过程，而且提高了成本效率。
