  Chronobiotic activity of N-[2-(2,7-dimethoxyfluoren-9-yl)ethyl]-propanamide. Synthesis and melatonergic pharmacology of fluoren-9-ylethyl amides

  摘要：

  A series of fluoren-9-yl ethyl amides (2) were synthesized and evaluated for human melatonin MT1 and MT2 receptor binding. N-[2-(2,7-dimethoxyfluoren-9-yl)ethyl]propanamide (2b) was selected and evaluated in functional assays measuring intrinsic activity at the human MT1 and MT2 receptors and demonstrated full agonism at both receptors. The chronobiotic properties of 2b were demonstrated in both acute and chronic rat models where 2b produced an acute phase advance of 32 min at 1 mg/kg and chronically entrained free-running rats with a mean effective dose of 0.23 mg/kg. Compound 2b is significantly less efficacious than melatonin in constricting human coronary artery. (C) 2004 Elsevier Ltd. All rights reserved.

  RhII重氮催化的芳族化合物分子间CH芳基化反应

  摘要：

  我们通过重氮（II）催化的重氮醌与芳族CH芳基化反应开发了联芳基的有效合成方法。新的联芳基合成可以在温和和中性条件下进行，而无需指导基团螯合辅助。该反应具有多种功能，可适用于多种芳族化合物。CH芳基化反应的区域选择性通常很高且可预测。该方法的合成实用性通过一系列药物和功能材料的后期修饰以及转甲状腺素蛋白淀粉样蛋白抑制剂的短暂合成得以证明。

• Oxygenative and Dehydrogenative [3 + 3] Benzannulation Reactions of α,β-Unsaturated Aldehydes and γ-Phosphonyl Crotonates Mediated by Air: Regioselective Synthesis of 4-Hydroxybiaryl-2-carboxylates

  Regioselective synthesis of 4-hydroxybiphenyl-2-carboxylates via the base-mediated oxygenative [3 + 3] benzannulation reaction of alpha,beta-unsaturated aldehydes and gamma-phosphonyl crotonates is reported. A hydroxyl group is installed in the final product on the originally phosphorus-bound carbon via a novel oxygenative and dehydrogenative transformation. The reaction proceeds rapidly in an open flask, uses atmospheric oxygen as an oxidant, and affords good yields of substituted biaryl phenols.

  We developed an efficient synthesis of biaryls by a dirhodium(II)‐catalyzed aromatic C−H arylation with diazo quinones. The new biaryl synthesis can be performed under mild and neutral conditions and without directing group chelation assistance. The reaction tolerates various functionalities and is applicable to a broad range of aromatics. The regioselectivity of the C−H arylation was often high and
