  摘要：

  基于酮氧化，采用催化HBr和DMSO，然后通过咪唑与醛的缩合反应，开发了一种单罐模块化方法，用于合成2,4（5）-二取代的咪唑。该方法提供了二十九个二取代的NH-咪唑（23％-85％的产率）。通过采用这种氧化-缩合方案，然后在咪唑环中进行溴化和Suzuki偶联，得到三取代的NH-咪唑（23％-69％，三步法），实现了三步合成20种激酶抑制剂的过程。该方法还用于合成已知抑制剂GSK3037619A。

• Base-Mediated Syntheses of Di- and Trisubstituted Imidazoles from Amidine Hydrochlorides and Bromoacetylenes
  作者：Xiao Yun Chen、Ulli Englert、Carsten Bolm

  DOI：10.1002/chem.201502707

  日期：2015.9.14

  A new transition metal‐free method for the preparation of substituted imidazoles from easy‐to‐handle amidine hydrochlorides and bromoacetylenes has been developed. The reactions proceed in air and use inexpensive K2CO3 as base. Additions of 2,2′‐bipyridine and water have beneficial effects on the product yields. Various di‐ and trisubstituted imidazoles have been prepared in good yields (up to 88 %)

• Anticonvulsant activity of 2,4(1H)-diarylimidazoles in mice and rats acute seizure models

  2,4(1H)-Diarylimidazoles have been previously shown to inhibit hNaV1.2 sodium (Na) channel currents. Since many of the clinically used anticonvulsants are known to inhibit Na channels as an important mechanism of their action, these compounds were tested in two acute rodent seizure models for anticonvulsant activity (MES and scMet) and for sedative and ataxic side effects. Compounds exhibiting antiepileptic activity were further tested to establish a dose response curve (ED(50)). The experimental data identified four compounds with anticonvulsant activity in the MES acute seizure rodent model (compound 10, ED(50) = 61.7 mg/kg; compound 13, ED(50) = 46.8 mg/kg, compound 17, ED(50) = 129.5 mg/kg and compound 20, ED(50) = 136.7 mg/kg). Protective indexes (PI = TD(50)/ED(50)) ranged from 2.1 (compound 10) to greater than 3.6 (compounds 13, 17 and 20). All four compounds were shown to inhibit hNaV1.2 in a dose dependant manner. Even if a correlation between sodium channel inhibition and anticonvulsant activity was unclear, these studies identify four Na channel antagonists with anticonvulsant activity, providing evidence that these derivatives could be potential drug candidates for development as safe, new and effective antiepileptic drugs (AEDs).

• A Practical Synthesis of 2,4(5)-Diarylimidazoles from Simple Building Blocks
  作者：Valentina Zuliani、Giuseppe Cocconcelli、Marco Fantini、Chiara Ghiron、Mirko Rivara

  DOI：10.1021/jo070187d

  日期：2007.6.1

  A simple and efficient approach to selectively obtain 2,4(5)-diarylimidazoles suppressing formation of 2-aroyl-4(5)-arylimidazoles is described. The yield of each of the two products strongly depends on the reaction conditions employed. This reaction provides a simple method to prepare small libraries of biologically active compounds by parallel synthesis.
