• CuI-Catalyzed Amination of Arylhalides with Guanidines or Amidines: A Facile Synthesis of 1-<i>H</i>-2-Substituted Benzimidazoles
  作者：Xiaohu Deng、Heather McAllister、Neelakandha S. Mani

  DOI：10.1021/jo900912h

  日期：2009.8.7

  CuI/L5 (N,N′-dimethylethylenediamine) proves to be an efficient catalyst system for the amination of arylhalides with guanidines. The same catalyst system is then successfully applied to the one-step synthesis of 1-H-2-amino-benzimidazoles through tandem aminations of 1,2-dihaloarenes in modest yields. This methodology is also applicable for the preparation of 1-H or 1-substutituted 2-aryl- or 2-alkyl-benzimidazoles

  事实证明，CuI / L5（N，N'-二甲基乙二胺）是一种用于将芳基卤化物与胍胺化的有效催化剂体系。然后将相同的催化剂体系成功地通过1,2-二卤代芳烃的串联胺化以适度的产率成功地一步合成1- H -2-氨基-苯并咪唑。该方法学也可用于制备1- H或1-取代的2-芳基-或2-烷基-苯并咪唑。

  Styrylamidines are prepared by treating styrylsulfonylamidines with base. The styrylamidines are effective in the prevention of aggregation of blood platelets and as analgesics. Compounds of the invention are also useful as anticonvulsants, diuretics and antihypertensive agents. The styrylsulfonylamidines of the invention which serve as precursors to the styrylamidines also have analgesic properties. Illustrative of the styrylamidines of the present invention are 4-amino-N-(4-aminostyryl)benzamidine and N-(3,4-dichlorostyryl)acetamidine. An example of a styrylsulfonylamidine is N-(styrylsulfonyl)acetamidine.

• A new improved method for the synthesis of 2,4-diarylpyrimidines starting from 2,2,2-trichloroethylideneacetophenones
  作者：Antonio Guirado、Enrique Alarcón、Yesica Vicente、Raquel Andreu

  DOI：10.1016/j.tetlet.2013.07.075

  日期：2013.9

  2-Trichloroethylideneacetophenones reacted with benzamidines leading to novel 2,6-diaryl-6-hydroxy-4-trichloromethyl-1,4,5,6-tetrahydropyrimidines in near quantitative yields. These compounds were efficiently dehydrated to obtain previously unknown 2,4-diaryl-6-trichloromethyl-1,6-dihydropyrimidines, which were able to undergo aromatisation via chloroform elimination to give 2,4-diarylpyrimidines in high

  已经开发了一种有利的2，4-二芳基嘧啶的新方法。2,2,2-三氯亚乙基苯乙酮与苄am反应，以接近定量的产率得到新型的2,6-二芳基-6-羟基-4-三氯甲基-1,4,5,6-四氢嘧啶。这些化合物被有效地脱水以获得先前未知的2,4-二芳基-6-三氯甲基-1,6-二氢嘧啶，这些化合物能够通过氯仿消除进行芳构化，从而以高收率得到2,4-二芳基嘧啶。该方法的主要改进在于避免了二氢嘧啶中间体的氧化脱氢。该制备过程也已经适应于一锅法方案。
