    名称:
    具有增强的酸度和可调节的催化选择性的金属有机骨架中的手性磷酸。
    摘要:
    通过在空间上阻止手性磷酸的配位,可将它们引入铟基金属有机骨架(In-MOF)中。该概念导致了由三个对映体纯的1,1'-双酚-磷酸衍生的四羧酸酯连接基构建的具有不同网络拓扑结构的三个手性多孔3D In-MOF的合成。更重要的是,与未固定的酸相比,所有未配位的磷酸基团在通道内周期性排列并且显示出显着增强的酸度。这有助于布朗斯台德酸催化不对称缩合/胺加成和亚胺还原。可以通过改变取代基来调节对映体选择性(最高> 99%ee),以实现与MOF中空间大基团浓度的几乎线性相关。

  • Highly Stable Zr(IV)-Based Metal–Organic Frameworks with Chiral Phosphoric Acids for Catalytic Asymmetric Tandem Reactions

    Heterogeneous Brønsted acid catalysts featuring high porosity, crystallinity, and stability have been of great interest for both fundamental studies and practical applications, but synthetically, they still face a formidable challenge. Here, we illustrated a ligand design strategy for directly installing chiral phosphoric acid catalysts into highly stable Zr-MOFs by sterically protecting them from coordinating
    具有高孔隙率、结晶度和稳定性的多相 Brønsted 酸催化剂在基础研究和实际应用中都引起了极大的兴趣,但综合起来,它们仍然面临着巨大的挑战。在这里,我们展示了一种配体设计策略,通过在空间上保护它们免于与属离子配位,将手性磷酸催化剂直接安装到高度稳定的 Zr-MOF 中。从对映体纯的 4,4',6,6'-四(苯甲酸酯)和 - 制备了一对骨架式为 [Zr6O4(OH)8(H2O)4(L)2] 的手性多孔 Zr(IV)-MOFs 1,1'-spirobiindane-7,7'-磷酸的四(2-萘甲酸配体。它们具有相同的拓扑结构,但通道大小不同,并且都表现出对、酸和碱的优异耐受性。与非固定酸相比,均匀分布在骨架内的磷酸的布朗斯台德酸度显着增强。这不仅促进了不对称双组分串联缩醛化、Friedel-Crafts 和iso-Pictet-Spengler 反应的催化,而且促进了不对称三组分串联脱缩醛化-缩醛化和

    2-aminobenzamide and aldehydes, catalyzed by a novel chiral organocatalyst, was realized. The organocatalyst was found to be very effective and highly enantioselective for such cascade reactions at room temperature, affording 2,3-dihydroquinazolinones in excellent yields (up to 99%) with enantiomeric excesses of up to 97%. The best level of stereocontrol was obtained for aromatic/aliphatic aldehydes with ortho

    in-depth intersection of supramolecular chemistry and asymmetric catalysis due to its unique advantages in building chiral catalyst libraries and regulating performance of catalysts. Herein, we combine crown ether based host–guest chemistry with chiral phosphoric acid mediated asymmetric catalysis to actualize the supramolecular regulation of catalytic asymmetric two-component tandem acetalization
    超分子不对称催化由于其在构建手性催化剂库和调节催化剂性能方面的独特优势而产生于超分子化学和不对称催化的深入交叉。在此,我们将基于冠醚的主客体化学与手性磷酸介导的不对称催化相结合,以实现催化不对称双组分串联缩醛化反应的超分子调控。与没有主客体相互作用的催化反应相比,添加碱属客体后,产率提高了72%,对映选择性提高了13%,证明了这种超分子调控策略的巨大优势。

    A Sc(OTf)(3)-catalyzed intramolecular amidation of imines with a novel fluorous bis(oxazolines) as ligand is presented. The corresponding chiral dihydroquinazolinones were obtained in 76-94% yield with enantioselectivities up to 98%. The fluorous ligand can be easily recovered and reused at least three times without significant loss of enantioselectivity. (C) 2014 Elsevier B.V. All rights reserved.

    The asymmetric condensation/amine addition cascade sequence of 2-aminobenzamides and aldehydes catalyzed by chiral spirocyclic SPINOL-phosphoric acids was realized. SPINOL-phosphoric acid 1j was found to be a general, highly enantioselective organocatalyst for such cascade reactions at room temperature, affording 2,3-dihydroquinazolinones in excellent yields (up to 99%) with good to excellent ee's (up to 98%). The best level of stereocontrol was obtained for aromatic aldehydes with an ortho substituent.
