  Electronic Effects of Ring Substituents on Triplet Benzylic Biradicals

  摘要：

  UV irradiation of alpha-(o-alkylphenyl)acetophenones with a methoxy or cyano substituent para to the o-alkyl group of the alpha-aryl ring has revealed that a methoxy group slightly increases the stereoselectivity but not the quantum yield of indanol formation, whereas a cyano group greatly lowers both diastereoselectivity and quantum efficiency, confirming the likelihood that hydrogen-bonding of the hydroxy group to the alpha-phenyl ring plays an important role in the cyclization of the photogenerated triplet 1,5-biradical intermediates.

• 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。
