A protocol for the synthesis of 2,4,6-trisubstituted pyridines from the β-nitrostyrenes, available substituted salicylic aldehydes and ammonium acetate was developed. The present strategy features high chemoselectivity and excellent tolerance for a broad range of functional groups, in which the β-nitrostyrenes generated from aldehydes and nitromethane, substituted salicylic aldehydes and ammonium acetate
开发了一种由β-硝基苯乙烯,可用的取代水杨醛和乙酸铵合成2,4,6-三取代吡啶的方案。本策略的特点是对广泛的官能团具有高化学选择性和优异的耐受性,其中分别采用由醛和硝基甲烷生成的β-硝基苯乙烯,取代的水杨醛和乙酸铵作为简单易用的底物。这种有效的方法可以快速访问各种结构多样的吡啶衍生物。X射线晶体学证实了两种典型产物的结构。
