in many biologically active natural products and pharmacologically relevant therapeutic agents. A new series of bistetrahydroquinolines (bis-THQs) was synthesized using imino Diels-Alder reactions between dialdehydes, anilines and N-vinyl-2-pyrrolidone (NVP). The notable features of this procedure are mild reaction conditions, greater selectivity and good yields of products. In addition, the inhibitory
四氢喹啉环系统是在许多生物活性天然产物和药理学相关治疗剂中发现的单元。使用二醛、苯胺和 N-乙烯基-2-吡咯烷酮 (NVP) 之间的亚氨基 Diels-Alder 反应合成了一系列新的双四氢喹啉 (bis-THQ)。该方法的显着特点是反应条件温和,选择性更高,产品收率高。此外,还报道了一些选定衍生物对乙酰胆碱酯酶 (AChE) 和丁酰胆碱酯酶 (BuChE) 的抑制活性。这些活性化合物在 AChE 和 BuChE 结合位点内的可行结合模式通过分子对接实验进行预测,并且通过 MM-GBSA 近似的自由能计算来估计它们的结合亲和力。
