this DES as a valuable reaction medium, the three-component Povarov reactions between aromatic aldehydes, anilines and indene were studied obtaining a series of pharmacologically important indeno[2,1-c]quinolines in high yields with short reaction times. All the reactions proceeded efficiently using the eutectic mixture as an environmentally friendly solvent, which was reused up to three cycles. Moreover
为此,使用FTIR,RAMAN和TGA制备了低熔点的
尿素-
氯化锌混合物并进行了表征。此外,还测量并分析了诸如电导率,密度,pH和折射率等物理
化学性质随温度的变化。为了进一步扩大这种DES作为有价值的反应介质的用途,研究了芳香醛,
苯胺和
茚之间的三组分Povarov反应,获得了一系列具有重要药理意义的
茚并[2,1- c
喹啉高产且反应时间短。使用低共熔混合物作为环境友好的溶剂,所有反应均有效进行,可重复使用多达三个循环。此外,绿色度量分析表明,该协议为构建相同杂环系统的传统方法提供了绿色且非常有效的替代方法。
