• Two Stereoinduction Events in One C−H Activation Step: A Route towards Terphenyl Ligands with Two Atropisomeric Axes
  作者：Quentin Dherbassy、Jean‐Pierre Djukic、Joanna Wencel‐Delord、Françoise Colobert

  scaffolds—ortho‐orientated terphenyls presenting two atropisomeric Ar–Ar axes. These unusual structures were built up by using the C−H activation approach, and remarkably, both chiral axes were controlled with excellent stereoselectivity in a single transformation. During the reaction, not only does atroposelective functionalization of a biaryl precursor occur to establish one stereogenic axis, but an

  在这里，我们公开了原始手性支架的合成-呈现两个阻转异构Ar-Ar轴的邻位三联苯。这些不寻常的结构是通过使用CH活化方法建立的，并且值得注意的是，两个手性轴在一次转化中都具有出色的立体选择性。在反应过程中，不仅会发生联芳基前体的对映选择性官能化以建立一个立体轴，而且还会发生空前的对映立体选择性CH芳基化反应，从而生成第二个立体成因元素。这些对映体纯的邻位叔苯基具有原始的三维结构，因此为建立对映体纯的双齿配体（例如新的配体S / N-Biax和二膦酸BiaxPhos）库提供了独特的基础。

  A transition-metal-free indole synthesis using radical coupling of 2-halotoluenes and imines via the later-stage C–N bond construction was reported for the first time. It includes an aminyl radical generation by C–H cleaving addition of 2-halotoluenes to imines via the carbanion radical relay and an intramolecular coupling of aryl halides with aminyl radicals. One standard condition can be used for

  作者：Zhixiang Chen、Yongwen Jiang、Li Zhang、Yinlong Guo、Dawei Ma

  日期：2019.2.27

  A robust and practical protocol for preparing alkyl aryl ethers has been developed, which relies on using two types of ligands to promote Cu-catalyzed alkoxylation of (hetero)aryl halides. The reaction scope is very general for a variety of coupling partners, particularly for challenging secondary alcohols and (hetero)aryl chlorides. In case of coupling with aryl chlorides and bromides, two oxalic
