A novel and efficient method for the synthesis of 3-arylpyridines from allylamine/propanediamine and aldehydes by palladium/copper-catalyzed oxidative tandem cyclization has been developed. With this reaction, a series of desired 3-arylpyridines was synthesized in moderate yields via CC/CN bond formation and 6-endo/exo-trig cyclization.
开发了一种新颖有效的方法,通过钯/铜催化的氧化串联环化反应从烯丙基胺/丙二胺和醛合成3-芳基吡啶。通过该反应,经由CC / CN键形成和6-内/外-trig环化以中等收率合成了一系列所需的3-芳基吡啶。
