    摘要:
    过渡金属催化剂在现代有机和高分子化学中起着重要作用,使许多具有学术和工业意义的转变成为可能。但是,使用有机金属催化剂通常需要从反应产物中除去其残留物,这在制药工业中尤其重要。因此,开发有效且经济的去除金属污染的方法至关重要。在本文中,我们证明了可商购的1,4-双(3-异氰基丙基)哌嗪可用作Cu / TEMPO醇好氧氧化(Stahl氧化)和原子转移自由基聚合中的高效淬灭剂(QA)和铜清除剂。 ATRP)。质量检查的补充立即在各种条件下终止Cu介导的反应,形成易于与小分子和大分子分离的铜络合物。醛的纯化方案基于添加少量硅胶,然后进行质量检查和过滤。使用原位合成的QA @ SiO 2生成的铜含量通常低于5 ppm。聚合物的纯化仅涉及在THF中添加QA,然后进行过滤,即使在催化剂负载量较高的ATRP之后,也导致铜含量非常低的聚合物。此外,添加QA可以完全防止氧化炔烃-炔烃(Glaser)偶联。虽然

    utilization of a double Ugi fourcomponent macrocyclization for the assembly of macromulticycles with up to four different tethers, that is, hybrid cages. The innovation of this method rests on setting up the macromulticycle connectivities not through the tethers but through the bridgeheads, which in this case involve N‐substituted amino acids. Both dilution and metal‐template‐driven macrocyclization

    Multiple multicomponent macrocyclizations including bifunctional buildings blocks (MiBs) so far have relied almost exclusively on Ugi reactions. The efficient expansion to non-Ugi-MiBs is exemplified by the synthesis of tetra-β-lactam and bis-α-acyloxy carboxamide macrocycles based on multiple Staudinger and Passerini three-component reactions (3CR), respectively. A recent variation of the Passerini-3CR

The performance of these scavengers is compared and contrasted with other known techniques, such as silica gel filtration and the use of self‐scavenging catalysts. As a result, a new hybrid purification method is devised, which gives better results than using either a self‐scavenging catalyst or a scavenger alone. Additionally, isocyanide II is shown to be a deactivating

  • Architectural Chemistry: Synthesis of Topologically Diverse Macromulticycles by Sequential Multiple Multicomponent Macrocyclizations
    作者:Daniel G. Rivera、Ludger A. Wessjohann
    DOI:10.1021/ja809005k
    日期:2009.3.18
    How can conformationally restricted polyvalent molecules be accessed rapidly? A sequential approach involving two multiple multicomponent macrocyclizations including bifunctional building blocks (MiBs) with up to five Ugi-four-component reactions (Ugi-4CR) has been developed to produce nonsymmetric macromulticycles. Topologically diverse structures, such as nonsymmetric cryptands and clam-,and igloo-shaped macromulticycles were obtained in reaction sequences that comprise the incorporation of up to 13 building blocks by forming 20 new bonds without purification of intermediates. Cryptands were produced by a sequential-MiB procedure in which the Ugi-type functional groups of the second MiB are attached to the peptoid backbones from the first multicomponent macrocyclization. These macrobicycles show two completely new features; i.e., three different tether chains can be obtained in one pot, and tertiary amide bonds are used as bridgeheads. Alternatively, the same reaction sequence, i.e., MiB/deprotection/MiB, can be used to produce clam-shaped macrobicycles, demonstrated with a tetrafunctional cholanic steroid as a hinge moiety. Macrotetracycles endowed with igloo-type topologies are accessible by an advanced protocol featuring consecutive double and 3-fold Ugi-4CR-based macrocyclizations. Other building blocks than cholanic steroids employed include aryl, heterocyclic, polyether, and other recognition motifs. The examples given are a first-generation demonstration of an "architectural chemistry" that allows to construct three-dimensional multimotif covalent molecular "buildings" of unprecedented complexity by design.
