  摘要：

  描述了使用基于钌的复分解催化剂的 Z 选择性大环化的第一份报告。对于具有各种官能团和环大小的多种底物，Z 大环的选择性始终很高。同样的催化剂也用于 E 和 Z 大环混合物的 Z 选择性乙烯醇解，提供纯 E 异构体。值得注意的是，只需要 1 个大气压的乙烯压力。这些方法已成功应用于几种嗅觉大环化合物的构建以及细胞毒性生物碱莫托泊明 C 的正式全合成。

  The synthesis of macrocycles is severely impeded by concomitant oligomer formation. Here, we present a biomimetic approach that utilizes spatial confinement to increase macrocyclization selectivity in the ring clos-ing metathesis of various dienes at elevated substrate concentration up to 25 mM using an olefin me-tathesis catalyst selectively immobilized inside ordered mesoporous silicas with defined

  伴随的低聚物形成严重阻碍了大环化合物的合成。在这里，我们提出了一种仿生方法，该方法利用空间限制来提高底物浓度高达 25 MM 的各种二烯闭环复分解中的大环化选择性，使用烯烃复分解催化剂选择性固定在具有确定孔径的有序介孔二氧化硅内. 通过这种方法，大（单）环化 (MMC) 产物与由无环二烯复分解聚合产生的所有不需要的低聚产物 (O) 之间的比率从 0.55 增加，对应于用均相催化剂获得的 35% MMC 产物，高达 1.49，对应 60% MMC 产品。成功地建立了 MMC/O 比和基材与孔径比之间的相关性。用二甲基二甲氧基硅烷修饰内孔表面可以微调有效孔径并反转表面极性，这导致 MMC/O 比进一步增加至 2.2，对应于 > 68% MMC 产品。模型孔隙几何结构中的分子级模拟有助于使空间限制、特定（基材和产品）与孔隙表面的相互作用以及扩散传输之间复杂的相互作用合理化。这些效果可以通过合适的

  communicates the first example of polymer backbone metamorphosis affected by anionic 1,2-Brook rearrangement of acyl silane moieties. Introduction of the acyl silane functionality into a polymer backbone was achieved via acyclic diene metathesis copolymerization (ADMET) of diene 1 and two dienes. We demonstrate that, using organolithium species and cyanide as nucleophiles, the backbones of resulting copolymers

  本报告介绍了受酰基硅烷部分阴离子 1,2-Brook 重排影响的聚合物主链变态的第一个例子。通过二烯1的无环二烯复分解共聚 (ADMET) 将酰基硅烷官能团引入聚合物主链和两个二烯。我们证明，使用有机锂物质和氰化物作为亲核试剂，可以触发所得共聚物的主链进行高效的 1,2-Brook 重排，从而将聚（酰基硅烷）转化为聚（甲硅烷基醚）。此外，1,2-Brook 重排的碳负离子中间体可以被酮亲电试剂拦截，从而产生在主链和侧链官能团中具有季立体中心的聚合物。这种聚合物骨架的结构编辑为含硅聚合物提供了一种新的逆合成范式，这是传统方法无法获得的。

  Two tungsten-based catalysts have been selectively immobilized within the pores of ordered mesoporous silica materials. X-ray absorption spectroscopy confirm the structural integrity of the catalysts. Compared to the homogenous analogues, the immobilized tungsten-catalysts exhibit a substantially increased macrocyclization- and Z-selectivity, which allow for the use of high substrate concentrations

  Oligomerization is kinetically favored in RCM reactions catalyzed by RuCl2(PCy3)(IMes)(=CHPh), for a range of unhindered , alpha,omega-dienes leading to large or medium-sized rings, even at dilutions designed to minimize intermolecular reaction. Reversible metathesis (i.e., ethenolysis) is inhibited by rapid volatilization of ethylene. At appropriately high dilutions, however, the RCM products are efficiently liberated by backbiting.
• Highly Selective Macrocycle Formations by Metathesis Catalysts Fixated in Nanopores

  Ruthenium-based metathesis catalysts immobilized on mesocellular siliceous foam (MCF) bearing large nanopores proved highly efficient and selective for macrocyclic ring-closing metathesis (RCM). Kinetic studies revealed that the homogeneous counterpart exhibited far higher activity that accounted for more oligomerization pathways and resulted in less macrocyclization products. Meanwhile, the immobilized catalysts showed lower conversion rates leading to higher yields of macrocyclic products in a given reaction time, with conversion rates and yields dependent upon pore size, catalyst loading density, and linker length. The macrocycle formations via RCM were accelerated by increasing the pore size and decreasing the catalyst loading density while retaining the comparably high yield. The catalysts immobilized on MCF, of which silica surface is rigid and pores are relatively large, showed high conversion rates and yields compared with an analogue immobilized on TentaGel resins, of which backbone becomes flexible upon swelling in the reaction medium. It is noteworthy that the selectivity for the macrocyclic RCM can be significantly improved by tuning the catalyst initiation rates via immobilization onto the support materials in which well-defined three-dimentional network of large nanopores are deployed.
