  with copper nanoparticles, have been prepared using a novel approach to the pre-existing methods. Their properties and characteristics have been studied using different techniques including UV-vis, XPS, TGA, ICP-AES, VSM, CHN, XRD, SEM-EDAX and TEM analysis. The Cu/NCNTs show nanocatalytic activity for the synthesis of four component pyridine derivatives and selective reduction of nitroarenes to their

  Here, we report a facile synthetic protocol to access a series of ethyl 5-cyano-2-methyl-4-aryl-6-(arylamino)nicotinates and ethyl 4-hydroxy-2-(4-nitroaryl)-5-oxo-1-aryl-2,5-dihydro-1H-pyrrole-3-carboxylates using tetragonal nano-ZrO2 as reusable catalyst. It was observed that the ZrO2 nanoparticles were stable during reaction and apparently no leaching of Zr-content occurred when the catalyst was

• FeCl₃-Catalyzed Four-Component Nucleophilic Addition/Intermolecular Cyclization Yielding Polysubstituted Pyridine Derivatives
  作者：Xinwei He、Yongjia Shang、Zhiyu Yu、Mei Fang、Yao Zhou、Guang Han、Fuli Wu

  DOI：10.1021/jo5014383

  日期：2014.9.19

  We report an efficient route to pyridine derivatives via an FeCl3-catalyzed four-component nucleophilic addition/intermolecular cyclization. This simple fragment assembly strategy uses mild conditions and affords a broad range of polysubstituted pyridines in moderate to good yield from simple and readily available starting materials. A plausible mechanism for this process is proposed.
