已经公开了芳基化吡啶的有效碱催化合成。这一涉及共轭乙炔和取代的苄胺的反应顺利进行,产生了三芳基取代的吡啶,它们是生物学相关的化合物,在 N,N-二甲基甲酰胺 (DMF) 中,在空气中,在 140 °C 下,以 K2CO3 为催化剂,产率良好至优异。
An efficient base-catalyzed synthesis of arylated pyridines has been disclosed. This reaction involving conjugated acetylenes and substituted benzylamines proceeded smoothly, giving rise to tri-aryl substituted pyridines which are biologically relevant compounds in good to excellent yields in N,N-dimethylformamide (DMF) under air at 140 °C with K2CO3 as catalyst.
