AbstractIn this paper, the results of our studies on the catalyst-free synthesis of some new 6-aminouracils bearing naphthoquinone, benzo[a]phenazine, benzo[f]pyrido[2,3-b]quinoxaline, and benzo[f]quinoxaline substituents are reported. At first, 6-amino-5-(3,4-dioxo-1-naphthalenyl)uracil derivatives were synthesized from the reaction of various 6-aminouracils with 1,2-naphthoquinone in DMSO at 70 °C
摘要在本文中,我们的研究结果是无催化剂合成一些带有萘醌,苯并[ a ]吩嗪,苯并[ f ]吡啶基[2,3- b ]喹喔啉和苯并[ f ]喹喔啉的新型6-氨基尿嘧啶。报告了取代基。首先,由各种6-氨基尿嘧啶与1,2-萘醌在DMSO中于70°C的反应中合成6-氨基-5-(3,4-二氧-1-萘)尿嘧啶衍生物,收率良好。随后,将制得的6-氨基-5-(3,4-二氧-1-萘)尿嘧啶与各种邻位二胺在氯仿中回流条件下进行缩合反应,合成带有苯并[ a ]吩嗪的6-氨基尿嘧啶,苯并[ f ]吡啶基[2,3-b ]喹喔啉和苯并[ f ]喹喔啉衍生物。 图形概要
