  摘要：

  描述了镍催化的烯丙基硼酸频哪醇酯烯丙基 B(pin) 的对映选择性加成。该反应对二亚烷基酮非常有效，并有利于非对称底物中亚苄基位点的烯丙基化。该反应似乎是通过将二亚烷基酮底物转化为不饱和的 pi-烯丙基络合物 (I)，然后进行还原消除来进行的。当使用手性配体 14 时，一系列底物的对映选择性范围为 91% 至 94% ee。

  A bis-sulfoxide with a binaphthyl backbone is introduced as a readily available, chiral ligand entity in late-transition metal catalysis. Ligand p-tol-BINASO [where p-tol-BINASO is 1,1‘-binaphthalene-2,2‘-diyl-bis-(p-tolylsulfoxide)] is obtained in pure form in one single synthetic step from relatively cheap, commercially available starting materials. Precatalyst [(P,R,R)-p-tol-BINASO}RhCl]2 was synthesized

  it both ways: A novel class of chiral sulfoxide‐olefin ligands was synthesized from a single chiral source. These ligands were evaluated in rhodium‐catalyzed 1,4‐additions of arylboronic acids to electron‐deficient olefins, and remarkable olefin‐directed reversal of stereoselectivity (up to >99 % ee, R isomer; 98 % ee, S isomer) was observed when the reversal ligand pair L1 (branched olefin) and L2

  A new chiral phosphine–olefin ligand (S)-1 has been designed and synthesized from l-hydroxyproline via a short reaction sequence. It was examined for its efficiency in the rhodium-catalyzed asymmetric addition of arylboronic acids and a phenylzinc reagent to cyclic α,β-unsaturated ketones, giving 1,4-addition products with high enantioselectivities.
