  摘要：

  合成了FDA批准的非甾体抗炎药diflunisal的类似物，并将其评估为转甲状腺素蛋白（TTR）聚集（包括淀粉样蛋白原纤维形成）的抑制剂。对于26种化合物观察到高抑制活性。其中，八种在人血浆中对TTR表现出优异的结合选择性（结合化学计量比> 0.50，每个TTR四聚体理论上最多结合有2.0种抑制剂）。生物物理研究表明，这八种抑制剂可在168小时的时间内显着减慢四聚体的解离（淀粉样蛋白生成的速率决定步骤）。这似乎是通过基态稳定化来实现的，这提高了四聚体解离的动力学势垒。这八种抑制剂对WT TTR的动力学稳定作用进一步得到证实，淀粉样蛋白原纤维形成的速率随抑制剂浓度（pH 4.4）的增加而降低。TTR.18（2）和TTR.20（2）配合物的X射线共晶体结构揭示了18和20在TTR结合位点以相反的方向结合。将氟从18的间位移至20的邻位可逆转结合方向，使20的亲水性芳环在外部结合袋中取向，其中羧

  摘要：

  可以容易地衍生自苯酚的底物之间的交叉偶联由于苯酚的含量高而极具吸引力。在这里，我们报道了芳基甲苯磺酸盐和芳基三氟甲磺酸酯之间双重的镍/钯催化的还原交叉偶联。可以从一个容易获得的苯酚中仅一步之遥就获得两种底物。该反应具有宽泛的官能团耐受性和底物范围（> 60个实例）。此外，它显示出对空间效应的低敏感性，这是通过合成2,2'-二取代的联芳基和完全取代的芳基产物证明的。天然产品和药品中苯酚的广泛存在使简单的后期功能化成为可能，例如ezetimibe和酪氨酸。

• An alternative and facile purification procedure of amidation and esterification reactions using a medium fluorous Mukaiyama reagent
  作者：Masato Matsugi、Misaki Suganuma、Shoko Yoshida、Shohei Hasebe、Yoko Kunda、Kotaro Hagihara、Sayaka Oka

  DOI：10.1016/j.tetlet.2008.09.016

  日期：2008.11

  convenient methodology for the separation of a fluorous by-product using fluorous chemistry is described. A Mukaiyama coupling reagent bearing a medium fluorous tag, between 40% and 60% fluorine by weight, can be effectively separated from non-fluorous components by increasing the water content of the crude reaction mixture and subsequent filtration. Additional fluorous solid phase extraction is not necessary

This protocol has an excellent substrate scope and gives the desired aldehydes, ketones and esters in moderate to high yields.

  Primary amides, either aliphatic or aromatic, are easily converted to the corresponding esters via reflux in lower primary alcohols in the presence of KHSO4. Secondary amides lead to complicated mixtures under analogous conditions, whereas tertiary amides were inert. Use of isopropyl alcohol resulted in the formation of product at slower rate and lower yield along with side products, whereas, use of
