  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.

• Ruthenium(II)-catalyzed Arylation of <i>ortho</i>-C–H Bonds in 2-Aroyl-imidazoles with Aryl Halides

  日期：2021.4.5

  The ruthenium(II)-catalyzed ortho-C−H arylation of 2-aroyl-imidazoles with aryl bromides and chloride is reported. An imidazole ring functions both as a masked ester and a directing group for C−H activation. A variety of functional groups are tolerated under the reaction conditions. The arylated final products could be easily converted into the corresponding esters and amide.

  报道了钌（II）催化的2-芳酰基咪唑与芳基溴化物和氯化物的邻位CH芳基化反应。咪唑环既起掩蔽酯的作用，又起CH活化的指导基团的作用。在反应条件下可以耐受多种官能团。芳基化的最终产物可以容易地转化成相应的酯和酰胺。
