  Heteroleptic ruthenium(II) complexes of 2-(2-pyridyl)benzimidazoles: A study of catalytic efficiency towards transfer hydrogenation of acetophenone

  摘要：

  Six ruthenium(II) complexes ([RuCl2(p-cymene)(L1-6)], SD1-6, (L1-6: bidentate pyridyl-benzimidazole ligands)) were synthesized from [RuCl2(p-cymene)](2) dimer and bidentate pyridyl-benzimidazole ligands. The compounds were characterized by elemental analysis, IR, UV-Vis, NMR and X-ray diffraction. The synthesized Ru(II) complexes (SDI-6) were tested as catalysts for the catalytic transfer hydrogenation (CH) of acetophenone to secondary alcohols in the presence of KOH using 2-propanol as a hydrogen source at 82 degrees C. All complexes were active catalysts for TM of acetophenone with good yields under mild conditions (after 15 min, yields of up to 91%). (C) 2014 Elsevier Ltd. All rights reserved.

  A series of novel 2-pyridylbenzimidazole derivatives was rationally designed and synthesized based on our previous studies on benzimidazole 14, a CB1 agonist used as a template for optimization. In the present series, 21 compounds displayed high affinities with Ki values in the nanomolar range. JM-39 (compound 39) was the most active of the series (KiCB1 = 0.53 nM), while compounds 31 and 44 exhibited similar affinities to WIN 55212-2. CoMFA analysis was performed based on the biological data obtained and resulted in a statistically significant CoMFA model with high predictive value (q2 = 0.710, r2 = 0.998, r2pred = 0.823).

  基于我们之前对用于优化模板的CB1激动剂苯并咪唑14的研究，我们合理设计并合成了一系列新型2-吡啶基苯并咪唑衍生物。在本系列化合物中，21种化合物显示出高亲和力，Ki值在纳摩尔范围内。JM-39（化合物39）是该系列中活性最高的（KiCB1 = 0.53 nM），而化合物31和44显示出与WIN 55212-2相似的亲和力。基于获得的生物学数据进行了CoMFA分析，并得到了一个统计学上显著且具有高度预测价值的CoMFA模型（q2 = 0.710，r2 = 0.998，r2pred = 0.823）。
