  Development of an efficient ruthenium catalyzed synthetic process and mechanism for the facile conversion of benzothiazoles to orthanilic acids

  摘要：

  Ruthenium-Schiff base complex catalyzed efficient protocol has been developed for the synthesis of orthanilic acids from benzothiazoles in good to excellent yields using N-haloamines. Hexa-coordinated ruthenium complex with Schiff base and triphenylphosphine ligands has been prepared and its catalytic function was invented for the synthesis of orthanilic acids. The synthetic process utilizes our efficient method for the selective and preferential oxidation of thiazole ring of benzothiazoles using N-haloamines without effecting phenyl ring. The detailed catalytic, mechanistic and kinetic investigations have been made for the synthetic reactions. Solvent isotope studies have been made in H2O-D2O and the reactions were carried out at different temperatures. Under the identical set of conditions, the kinetics of catalyzed reactions has been compared with uncatalyzed reactions and found that the catalyzed reactions are 9-11 folds faster. The catalytic constants (K-c) have been calculated for each N-haloamine at different temperatures and the values of activation parameters with respect to the catalyst have been evaluated. Spectroscopic evidence for the formation of 1:1 complex between N-haloamine and ruthenium has been obtained. The observed results have been explained by a plausible mechanism and the related rate law has been deduced. (C) 2010 Elsevier B.V. All rights reserved.

  摘要：

  一组新的氮杂双环芳基酰胺已被鉴定为α7nAChR的有效和选择性激动剂。采取了两管齐下的方法来改善先前公开的alpha7 nAChR激动剂PNU-282,987的潜在hERG耐受性，同时保持该化合物的其他所需药理特性。第一种方法涉及对PNU-282,987的芳基羧酸片段的进一步研究，而第二种方法则侧重于对PNU-282,987的氮杂双环胺部分的修饰。每个系列中最好的化合物的特点是脑部快速渗透，在大鼠中具有良好的口服生物利用度，并在大鼠P50听觉感觉门控试验中显示出体内功效。每个系列（1h，1o，2a，9a和18a）中至少有一个类似物表现出比PNU-282,987更高的hERG安全性。
