A series of N-ethyl phthalimide esters 4(a-n) were synthesized and characterized by spectroscopic studies. Further, the molecular structure of majority of compounds were analysed by single crystal X-ray diffraction studies. The X-ray analysis revealed the importance of substituents on the crystal stability and molecular packing. All the synthesized compounds were tested for in vitro antioxidant activity by DPPH radical scavenging, FRAP and CUPRAC methods. Few of them have shown good antioxidant activity.
我们合成了一系列 N-乙基邻苯二甲酰亚胺酯 4(a-n),并通过光谱研究对其进行了表征。此外,还通过单晶 X 射线衍射研究分析了大多数化合物的分子结构。X 射线分析表明了取代基对晶体稳定性和分子堆积的重要性。通过 DPPH 自由基清除法、FRAP 法和 CUPRAC 法测试了所有合成化合物的体外抗氧化活性。其中一些化合物显示出良好的抗氧化活性。
