([TMBSED][OMs]2) was employed for the synthesis of piperidines and dihydropyrrol-2-ones via one-pot multi-component reactions in simple and green processes. This pseudo five-component reaction of aromatic aldehydes, anilines and alkyl acetoacetates was carried out under reflux conditions in ethanol to afford substituted piperidines. Also, dihydropyrrol-2-one derivatives were synthesized by means of four-component
N,N,N',N'-四甲基-N,N'-双(磺基)乙烷-1,2-甲磺酸二胺 ([TMBSED][OMs]2) 用于合成哌啶和二氢吡咯-2-在简单和绿色的过程中通过一锅多组分反应进行生产。这种芳香醛、苯胺和乙酰乙酸烷基酯的假五组分反应在回流条件下在乙醇中进行,得到取代的哌啶。此外,二氢吡咯-2-one 衍生物通过各种胺、乙炔二羧酸二烷基酯和甲醛在室温下在乙醇中的四组分反应合成。目前的方法有几个优点,如产率高、后处理容易、反应时间短,以及利用温和和清洁的反应条件。
