Highly regioselective reaction of some substituted 2,4-dichloroquinolines with symmetrical 1,4-dihydropyridines, leading to novel quinoline derivatives of DHPs, has been achieved in the presence of powdered K2CO3, as a mild and efficient base, at moderate temperature. All the synthesized compounds were characterized by use of IR, NMR, and mass spectral data.
在温和、高效的碱 K2CO3 粉末存在下,一些取代的 2,4-二氯喹啉与对称的 1,4-二氢吡啶在中等温度下发生了高区域选择性反应,生成了新型的二氢吡啶喹啉衍生物。利用红外光谱、核磁共振和质谱数据对所有合成化合物进行了表征。
