  阴极材料决定联芳基酮肟化学C-H官能化的产物选择性

  摘要：

  多环N-杂芳族化合物及其相应的N-氧化物的合成是通过联芳基酮肟的电化学CH功能化开发的。当使用Pt阴极时，肟底物会经历脱氢环化反应，从而导致空前地获得各种N-杂芳族N-氧化物。通过顺序地阳极促进的脱氢环化作用和最初形成的N-氧化物中N-O键的阴极裂解，采用Pb阴极，将电合成的产物切换为脱氧的N-杂芳族化合物。

  N-Propargylic β-Enaminones: Common Intermediates for the Synthesis of Polysubstituted Pyrroles and Pyridines

  摘要：

  N-Propargylic beta-enaminones have been used as common intermediates for the synthesis of polysubstituted pyrroles and pyridines. Best results have been obtained using DMSO as solvent. In the presence of CS(2)CO(3) N-propargylic beta-enaminones are cyclized to pyrroles in good to high yields, whereas omitting bases and using CuBr leads to the selective formation of pyridines.
