    日期:2018.10.5
    via a cascade transfer hydrogenation and dynamic kinetic resolution strategy is described. This protocol features broad substrate scope and good functional group tolerance and allows the rapid assembly of axially chiral biaryls in good to high yields with high to excellent enantioselectivities. In addition, such structural motifs may have potential applications in enantioselective catalysis as chiral
    描述了通过级联转移氢化和动态动力学拆分策略,空前的钌催化的烷基胺对醛的对苯二酸选择性还原胺化反应。该方案具有广泛的底物范围和良好的官能团耐受性,并允许以高至高收率和高至优异的对映选择性快速组装轴向手性联芳基。另外,这样的结构基序可以作为手性配体或催化剂在对映选择性催化中具有潜在的应用。

    synthesis include the construction of the all-carbon quaternary center at an early stage, a key double intramolecular SNAr step to introduce the spirocycles and the feasibility of operating on >100 g scale. Both enantiomers of O-SPINOL can be easily accessed through optical resolution with l-proline by control of the solvent. The chiral tridentate ligand O-SpiroPAP derived from O-SPINOL has been successfully
    我们在此提出了一种简便且无柱的合成路线,用于合成结构独特的氧杂-螺环二酚,称为 O-SPINOL。该合成的特点包括在早期构建全碳四元中心、引入螺环的关键双分子内 SNAr 步骤以及在 >100 g 规模上操作的可行性。O-SPINOL 的两种对映异构体都可以通过控制溶剂的 l-脯氨酸光学拆分轻松获得。衍生自 O-SPINOL 的手性三齿配体 O-SpiroPAP 已成功合成并应用于在温和反应条件下铱催化的桥联联芳基内酯的不对称氢化,以优异的产率和对映选择性(高达 99 % 产率和 >99% ee)。

    a broad substrate scope and good functional group tolerance and allows the rapid assembly of various valuable axially chiral biaryls in good to high yields (up to 92% yield) with high to excellent enantioselectivities (up to 96% ee). Moreover, this report represents a rare example that a carbonyl group of esters is reduced under homogeneous asymmetric CuH catalysis.

    A solution to the unmet synthetic challenge of achieving highly atropo-enantioselective transesterification of Bringmann's lactones has been realized, employing a chiral bifunctional amine thiourea as promoter. The synergistic activation of the lactones and alcohols/phenols by the respective thiourea and amine groups is crucial for achieving the highly enantioselective, high-yielding dynamic kinetic

    transfer of an alkoxide ligand from the chiral ligand sphere of Ti-TADDOLates 1 to cyclic carboxylic acid derivatives is described. The kinetic resolution of dioxolanones, azlactones and biaryl lactones by the Ti-TADDOLates affords, after recrystallization, ester products in highly enantioenriched form (er ≥ 97:3).
