1过硫酸钾促进2-炔芳基腈与亚磺酸钠的自由基串联环化: 构筑稠环环戊烯并[gh]菲啶显示文摘报道了一种以2-炔芳基腈和亚磺酸钠为原料,过硫酸钾为氧化剂,通过自由基串联环化反应一步构筑环戊烯并[gh]菲啶的新方法.该反应具有反应条件温和、原子经济性高、底物适应性较强等优势.利用此方法简便地合成了多种潜在的具有生物活性的4-磺化环戊烯并菲啶.陈志超 张红 周树锋 崔秀灵 2020有机化学2020,40,11:4
2Recyclable Carbon Nitride Nanosheet-Photocatalyzed Aminomethylation of Imidazo[1,2-a]pyridines in Green Solvent显示文摘An efficient and eco-friendly carbon nitride nanosheet(NM-g-C3N4)-catalyzed decarboxylative coupling reaction of imidazo-fused heterocycles(i.e.,imidazo[1,2-a]pyridines,benzo[d]imidazo[2,1-b]thiazole)with N-phenylglycines in dimethyl carbonate(DMC)has been developed.The toxic solvents,external oxidants,and restricted reaction conditions could be effectively avoided in this powerful and sustainable protocol.Remarkably,NM-g-C3N4 could be straightforwardly recovered by simple centrifugation and recycled and reused at least 7 times without an obvious decrease in catalytic activity.Tao Shi Yu-Ting Liu Shan-Shan Wang Qi-Yan Lv Bing Yu 2022Chinese Journal of Chemistry2022,40,1:0
3Micellar Catalysis:Visible-Light Mediated Imidazo[1,2-a]pyridine C—H Amination with N-Aminopyridinium Salt Accelerated by Surfactant in Water显示文摘A light-promoted metal-free protocol for the amination of imidazo[1,2-a]pyridines with N-aminopyridinium salt by the assistance of surfactants in water was reported,charactering mild and environmentally benign conditions,as well as great functional group tolerance.Micelles with negatively charged polar surface and hydrophobic core formed from sodium dodecyl sulfate serve as an ideal medium for visible-light mediated radical reaction of cationic pyridine salt and imidazo[1,2-a]pyridine in aqueous phase.The electrostatic interaction between positively charged N-aminopyridinium and negatively charged surface of micelles is of great significance in this method.Zhonglie Yang Kun Cao Xiaoyan Peng Li Lin Danchen Fan Jun-Long Li Jingxia Wang Xiaobin Zhang Hezhong Jiang Jiahong Li 2021Chinese Journal of Chemistry2021,39,12:0
