A facile and efficient microwave-assisted reaction of 1,8-naphthalic anhydride derivatives with primary amines, leading to the synthesis of 1,8-naphthalimides, has been developed. Subsequently, the free radical scavenging properties of the 1,8-naphthalimide derivatives were evaluated against 2,2-diphenyl-1-picrylhydrazyl (DPPH•). The results showed that the scavenging activities of compounds 2a, NBNA
已经开发了一种简便有效的微波辅助的1,8-萘酐衍生物与伯胺的反应,从而合成了1,8-萘二甲酰亚胺。随后,评估了1,8-萘二甲酰亚胺衍生物对2,2-二苯基-1-吡啶并肼基(DPPH •)的自由基清除性能。结果表明,化合物2a,NBNA,3b和3c的清除活性比常用的合成抗氧化剂2,6-二叔丁基-4-甲基苯酚(BHT)的清除活性更高,IC 50值分别为61.9、54.0、42.2和43.1μM。在萘部分的位置4处引入的酰亚胺基团以及在位置3处的硝基官能团是自由基清除活性的主要贡献者。
