    P-立体异构二磷酸ac的合成和碱金属离子络合。
    摘要:
    由于磷原子的高反转能垒,因此膦是构象稳定的,这使磷原子成为手性中心。因此,对映纯P-立体异构的12-,15-,18-和21-元脂肪族膦“二磷酸ac”是由仲P-立体异构双膦作为手性结构单元合成的。与苯并18-18二磷杂草酮6和苯并18皇冠6比较,研究了它们与碱金属离子的络合行为。15-,18-和21-元的二膦酸酯捕获碱金属离子,形成1:1金属络合物。观察到了独特的客体选择性,因为二磷杂草醚所包封的碱金属离子比普通冠醚更小;例如,18元的双磷ac与Na +的相互作用比K +的相互作用强。据推测,由于大的磷原子以及膦部分周围的空间位阻,二膦酸酯和普通冠醚之间的客体选择性差异是由腔体尺寸引起的。

    摘要:
    A new synthetic route to enantiopure P-stereogenic benzodiphosphacrowns using a P-stereogenic secondary bisphosphine as the key building block is reported. Syntheses of the enantiomer and P-stereogenic crowns with various ring structures, as well as deboranation of the crown compounds and subsequent reaction with a platinum complex, are described.

    probed as a catalyst in asymmetric hydrogenations of representative prochiral substrates, demonstrating high activity and good to excellent enantioselectivities. A mechanistic study revealed that 5 can be cleanly and stereoselectively converted to the tetrahydride species 6a, which is stable up to 0 °C and at higher temperatures slowly decomposes without the loss of hydrogen. The low-temperature (−80 °C)
    通过膦-硼烷方法制备旋光的C 2-对称的四膦4。其dirhodium配合物5在结构上得到了表征,并被用作代表性前手性底物的不对称氢化中的催化剂,证明了其高活性和良好至出色的对映选择性。机理研究表明,可以干净地和立体选择性地将5转化为四氢化物物种6a,该物种在0°C时稳定,并且在较高的温度下缓慢分解而不会损失氢。低温(-80℃)的反应图6a与甲基(ž)-α-乙酰氨基doc酸酯(MAC)干净地得到四氢化物配合物7,该四氢化物配合物7包含仅通过酰胺羰基配位的一分子底物分子,而底物的双键保持不配位。将温度升高到-40°C导致络合物7到8发生不可逆的异构化,这与7的区别仅在于配体的空间排列。与7至8的异构化同时进行的迁移插入产生三氢化物络合物9,其是前述的一氢化物中间体的类似物。当6a反应用MAC在过量MAC的存在下进行分离,释放的铑配合物被底物捕获,得到催化剂-底物配合物10,用多核NMR表征。与

    日期:2017.1
    Optically active macrocycles consisting of two P-stereogenic bisphosphine units and two π-conjugated linkers were synthesized via [2 + 2] cyclization. A clear Cotton effect was observed in the π–π* transition region of the π-conjugated units, indicating that the chirality is induced by the P-stereogenic bisphosphine moieties onto the π-conjugated linkers. Compared with model compounds, the orientation

  • P-Stereogenic Diphosphacrowns: Facile Incorporation of Aromatic Rings
    作者:Yasuhiro Morisaki、Yoshiki Chujo、Ryosuke Kato、Hiroyuki Watanabe
    DOI:10.3987/com-15-13324
    日期:——
    P-Stereogenic diphosphacrowns containing naphthalene and pyridine rings were synthesized. Facile incorporation of aromatic rings, and chains of different lengths, into the diphosphacrown skeleton was achieved by altering the electrophile in our previously reported synthetic method. Pyridine-containing diphosphacrown exhibited chiral recognition ability for chiral ammonium salts and carboxylic acids. This is the first example of chiral recognition using P-stereogenic diphosphacrowns. H-1 and P-31 NMR spectra indicated that the nitrogen, oxygen, and chiral phosphorus atoms contributed to the chiral recognition cooperatively.

    benzo‐18‐crown‐6. 15‐, 18‐, and 21‐Membered diphosphacrowns captured alkali metal ions to form 1:1 metal complexes. Unique guest selectivity was observed, as diphosphacrowns encapsulated smaller alkali metal ions than common crown ethers; for example, 18‐membered diphosphacrowns interacted more strongly with Na+ than K+. The difference in guest selectivity between diphosphacrowns and common crown ethers
