  Synthesis of 3,4-diaminobenzoyl derivatives as factor Xa inhibitors

  摘要：

  The coagulation factor Xa (FXa) plays a central role in the blood coagulation cascade. Recent studies have shown that FXa is a particularly attractive target for the development of oral antithrombotic agents. In view of the excellent pharmaceutical properties of 1,2-phenylenediamine-based FXa inhibitors and the reported structure activity relationship (SAR) analysis of FXa inhibitors, we designed and synthesized a series of 3,4-diaminobenzoyl-based FXa inhibitors. Intensive SAR studies on this new series led to the discovery of 3,4-dimethoxyl substituted compound 7b. 7b is a highly potent, selective, direct FXa inhibitor with excellent in vivo antithrombotic activity.

• Practical Chemoselective Acylation: Organocatalytic Chemodivergent Esterification and Amidation of Amino Alcohols with <i>N</i> ‐Carbonylimidazoles
  作者：Hope Nelson、William Richard、Hailee Brown、Abigail Medlin、Christina Light、Stephen T. Heller

  DBU-catalyzed esterification: A single esterification product was obtained from a molecule containing primary aniline, alcohol, phenol, secondary amide, and N−H indole groups. These acylation reactions are highly practical as they involve only readily available, inexpensive, and relatively safe reagents; can be performed on a multigram scale; and can be used on carboxylic acids directly by in situ formation

  化学选择性转化是高效有机合成的基石；然而，即使是简单的转化，如酰化反应，要实现这一目标也常常是一个挑战。我们报告说，N-羰基咪唑分别在吡啶鎓离子或 1,8-二氮杂双环 [5.4.0] undec-7-ene (DBU) 存在下能够催化化学发散的苯胺或醇酰化。两种酰化反应都显示出对目标基团的高而广泛的化学选择性。在 DBU 催化的酯化中观察到了前所未有的化学选择性水平：从含有伯苯胺、醇、苯酚、仲酰胺和N的分子中获得单一酯化产物-H吲哚基团。这些酰化反应非常实用，因为它们只涉及容易获得、便宜且相对安全的试剂；可以在多克规模上进行；并且可以通过原位形成酰基咪唑亲电试剂直接用于羧酸。

  作者：Shinzo Seko、Kunihito Miyake、Norio Kawamura

  DOI：10.1039/a901537j

  日期：——

  O-Alkylhydroxylamines, particularly O-methylhydroxylamine, aminate nitroarenes in the presence of a strong base and a copper catalyst to give aminonitroarenes in good yields. ortho- or para-Amination with respect to the nitro group takes place, and in some cases the ortho-aminated product is preferentially obtained. With 3-substituted nitrobenzenes where the substituent has a lone pair of electrons, preferential amination occurs at the 2-position to give the sterically most congested 3c–f, 14 and 22g.

  Supplementing an AHBA(−) mutant strain of Amycolatopsis mediterranei, the rifamycin producer, with a series of benzoic acid derivatives yielded new tetraketides containing different phenyl groups. These mutasynthetic studies revealed unique reductive properties of A. mediterranei towards nitro‐ and azidoarenes, leading to the corresponding anilines. In selected cases, the yields of mutaproducts (fermentation

  用一系列苯甲酸衍生物补充利福霉素生产者地中海淀粉样芽胞杆菌的AHBA（-）突变株，产生了含有不同苯基的新四酮化合物。这些突变合成研究揭示了地中海曲霉对硝基和叠氮芳烃的独特还原特性，从而导致了相应的苯胺。在某些情况下，诱变产物（用天然成分的化学制备类似物喂食细菌后分离出的发酵产物）的产率在一定范围内（最高118 mg L -1），使其可用作手性成分，用于进一步的合成努力。确定C6和C7的立体异构中心的构型为6 R，7 S一种代表性的四酮化合物。重要的是，当不能发生双环萘前体的形成时，并不总是阻止超过四酮化合物阶段的加工。通过形成十一烷基溴去甲蝶呤证明了这一点，该发现对利福霉素生物合成的进化发展有影响。
