    High-Load, Hybrid Si-ROMP Reagents
    摘要:
    The combination of norbornenyl-tagged (Nb-tagged) silica particles and functionalized Nb-tagged monomers for the generation of hybrid Si-ROMP reagents and scavengers is reported. Specifically Si-ROMP-derived bis-acid chloride, dichlorotriazine, and triphenylphosphine scavenger/reagents have been grafted from the surface of silica particles utilizing surface-initiated, ring-opening metathesis polymerization (ROMP). These hybrid polymeric materials combine the physical properties of current immobilized silica reagents and represent a key advancement in load by merging the inherent tunable properties of the ROMP-derived oligomers with silica supports for application in a parallel synthesis.

  • Spontaneous formation of PMB esters using 4-methoxybenzyl-2,2,2-trichloroacetimidate
    作者:Jigisha P. Shah、Christopher M. Russo、Kyle T. Howard、John D. Chisholm

    Carboxylic acids are converted to the corresponding 4-methoxybenzyl (PMB) esters with 4-methoxybenzyl-2,2,2-trichloroacetimidate in the absence of an acid catalyst. This operationally simple procedure is a highly effective method for the formation of PMB esters. The reaction is promoted by the carboxylic acids themselves in excellent yields (72–99%). Sterically hindered carboxylic acids, which provide
    在不存在酸催化剂的情况下,用4-甲氧基苄基-2,2,2-三氯乙亚氨酸酯将羧酸转化为相应的4-甲氧基苄基(PMB)酯。该操作简单的步骤是形成PMB酯的高效方法。羧酸本身以优异的产率(72–99%)促进了反应。与其他酰亚胺化合物提供较低收率的立体受阻羧酸,与反应性更强的PMB亚氨酸酯以较高的收率进行酯化。在带有α-立体中心的羧酸的情况下未观察到外消旋化,并且对于Z-α,β-不饱和酸未观察到异构化。因此,该方法可用于复杂或敏感底物的酯化反应中,其中更常见的技术会导致分解。

    approach for the activation of esters via a radical-mediated process enabled by a copper/Selectfluor system. A variety of para-methoxybenzyl esters derived from bulky carboxylic acids and amino acids can be easily converted into the corresponding acyl fluorides, directly used in the one-pot synthesis of amides and peptides. As a proof of concept, this method was applied to the iterative formation of sterically
    在本文中,我们描述了一种通过铜/ Selectfluor系统实现的自由基介导的过程来活化酯的新方法。衍生自庞大的羧酸和氨基酸的多种对甲氧基苄基酯可轻松转化为相应的酰基氟,直接用于酰胺和多肽的一锅法合成中。作为概念的证明,该方法被应用于空间位阻酰胺键的迭代形成。
  • Iron-catalysed highly selective hydroalkoxycarbonylation of alkynes using CO as C1 source

    Though precious and rare, late-transition metals have been extensively used in metal-catalysed carbonylation reactions in organic transformations. On the other hand, base metals are abundant and cheap, but their practical utilization in carbonylation reactions is rarely explored. Here, we report iron-catalysed hydroalkoxycarbonylation of alkynes to α,β-unsaturated esters in one pot. A readily available
    尽管珍贵且稀有,但后过渡金属已广泛用于有机转化中的金属催化羰基化反应。另一方面,贱金属丰富且廉价,但很少探索它们在羰基化反应中的实际应用。在这里,我们报道了铁催化炔烃一锅加氢烷氧基羰基化为α,β-不饱和酯。在二亚胺配体L7存在下,容易获得的铁前体 [Fe 2 (CO) 9 ]在 10 bar CO 压力下催化炔烃转化为 α,β-不饱和酯。这种操作简单的方案可耐受各种官能团,并可以轻松获得约 40 种 α,β-不饱和酯。通过将反应放大至 1 g 并制备防晒剂/抗真菌剂,已经证明了该反应的合成效用。动力学研究表明,对于铁催化剂,该反应近似为一阶反应,反应初始速率为3.6 × 10 -2 M h -1。使用核磁共振波谱进行的机理研究表明存在 [Fe-H] 中间体,而使用自由基捕获剂和 EPR 的对照实验表明反应中不存在任何自由基物质。
