  Synthesis and analgesic activity of some 1-benzyl-2-substituted-4,5-diphenyl-1H-imidazole derivatives

  摘要：

  In this study, derivatives of 1-benzyl-2-substituted-4,5-diphenyl-1H-imidazole were synthesized and their analgesic activity assayed in two tests. 1,2,4,5-Tetrasubstituted imidazole compounds were obtained by the treatment of purified imidazole compounds with benzyl chloride in the presence of sodium hydride. The structure elucidation of the compounds was performed by IR, H-1-NMR and mass spectroscopic data and elemental analysis results. Generally the prepared compound exhibited only moderate analgesic activity in mice at the dose of 100 mg/kg i.p.; however, a few of them exhibited good activity, almost equivalent to that of morphine at 1 mg/kg i.p. was observed. At the above dosage, no toxicity was observed for all compounds. (C) 2001 Elsevier Science S.A. All rights reserved.

  cellulose. Comparison and contrasts between the reactivity of copper (I) oxide supported onto different supports for these reactions are made. The reactivity of copper (I) oxide seems to be largely dependent on the nature of support and the most active catalyst for a particular reaction was further characterized by different spectroscopic techniques such as FTIR, XRD, TGA, XPS, SEM, TEM and AAS. The catalysts

  摘要已经使用更简单的方法研究了铜介导的C-杂原子，特别是C-N和C-O键的形成。在目前的工作中，各种底物（如胺，酚和醇）的乙酰化；2,4,5-三取代的咪唑的合成是使用简单且容易获得的原料完成的。通过用葡萄糖还原费林溶液，然后将其固定在不同的载体（如二氧化硅，HAP，碱性氧化铝和纤维素）上，就地合成了氧化铜（I）。对这些反应负载在不同载体上的氧化铜（I）的反应性进行了比较和对比。氧化铜（I）的反应性似乎在很大程度上取决于载体的性质，并且通过不同的光谱技术（例如FTIR，XRD，TGA，XPS，SEM，TEM和AAS）进一步表征了用于特定反应的最具活性的催化剂。发现该催化剂是稳定的，易于回收的，而活性没有任何明显的损失。 图形概要研究了固体负载的氧化铜（I）（其中固体负载为二氧化硅，HAP，纤维素和碱性氧化铝）在各种有机转化中的应用，其中特别强调了C–N和C–O键的形成反应。

  The molecular structures of the ruthenium(II) complexes 1-3 were determined by single-crystal X-ray diffraction. All complexes were used as catalysts for the one-pot three-component syntheses of 2,4,5-trisubstitued imidazole and 5-substituted 1H-tetrazole derivatives. The catalytic studies optimized parameters as solvent, temperature and catalyst. The catalysts revealed very active for a broad range
