  Biarylmethoxy isonipecotanilides as potent and selective inhibitors of blood coagulation factor Xa

  摘要：

  New chloro-substituted biarylmethoxyphenyl piperidine-4-carboxamides were synthesized and assayed in vitro as inhibitors of the blood coagulation enzymes factor Xa (fXa) and thrombin. An investigation of effects of the amidine and isopropyl groups attached at the piperidine nitrogen and 5-(halogenoaryl)isoxazol-3-yl groups as biaryl substituents led us to identify new compounds which proved to be selective fXa inhibitors, with inhibition constants in the low nanomolar range. The most potent compound 21e, that incorporates 2-Cl-thiophen-5-yl group as the P1 motif and 1-isopropylpiperidine P4 group, inhibited fXa with K-i value of 0.3 nM and very high selectivity over thrombin and some other tested serine proteases, achieving moderate levels of anticoagulant activity in the low micromolar range, as assessed by the prothrombin time clotting assay (PT2 = 3.30 mu M). Based on reliable docking simulations, molecular modeling provided a rationale for interpreting structure-activity relationships. The predicted binding modes highlighted the structural requirements for addressing the subsites S1 and S4 of the fXa enzyme. (C) 2010 Elsevier B.V. All rights reserved.

  有机锗烷的正交纳米颗粒催化。

  摘要：

  尽管纳米颗粒被广泛用作催化剂，但与均相分子或本体非均相催化剂相比，其潜在的引发特权转化的能力知之甚少。我们在本文中证明（并合理化）纳米颗粒在芳基卤化物与芳基锗烷的交叉偶联中显示出与分子催化剂正交的反应性。芳基锗烷在Ln Pd0 / Ln PdII催化中不反应并允许已存在的偶合体选择性官能化，但它们在Pd纳米颗粒条件下显示出优异的反应活性，超过了已建立的偶合体（如ArBPin和ArBMIDA），并且具有耐空气性，无碱基且正交获得有价值且具挑战性的联芳基图案。与众所周知的不稳定的多氟芳基和2-吡啶基硼酸相反，相应的德语非常稳定并且易于耦合。我们的机理和计算研究为纳米颗粒催化提供了明确的支持，并表明由于芳基锗烷的电子丰富，它们优先通过亲电子芳族取代反应，进而优先被亲电子性更高的纳米颗粒活化。

  F for fast: The perfluorinated solvent C6F14 is the key to a new variant of the Balz–Schiemann reaction for the synthesis of fluorinated arenes. Triazenes are converted into fluoroarenes under mild conditions on a support and in solution (see scheme). The method is straightforward and inexpensive, and yields previously difficult‐to‐prepare fluoroarenes in high purity.

  give various biaryls in good yields. It is worthwhile to note that the all-carbon-substituted arylsilanes, stable towards moisture, acid, and base and easily accessible, serve as a highly practical alternative to their aryl(halo)silane counterparts. A catalyst system consisting of [(η3-C3H5)PdCl]2 and 2-[2,4,6-(i-Pr)3C6H2]-C6H4PCy2 and use of TBAF⋅3 H2O in THF-H2O are effective especially for the cross-coupling

  Cross-coupling of (hetero)arylthiols with arylzinc reagents via C–S cleavage was performed under transition-metal-free conditions. The reaction displays a wide scope of substrates and high functional-group tolerance. Electron-rich and -deficient (hetero)arylthiols and arylzinc reagents can be employed in this transformation. Mg2+ and Li+ ions were demonstrated to facilitate the reaction.

  作者：Joseph Miller、John Dankwardt、Jonathan Penney

  DOI：10.1055/s-2003-40873

  日期：2003.8

  Aryl nitriles have been found to participate in cross-coupling and amination reactions via nickel-catalyzed activation of the C-CN bond. With the development of these synthetically useful transformations, aryl nitriles can now be considered along with aryl halides and sulfonates as viable substrates for these types of reactions.
