5-tri-O-benzoyl-β-D-ribofuranose afforded the corresponding protected nucleosides, respectively. Nitration of each of the theophylline and 3-benzy-1-methyllxanthine protected nucleosides yielded the corresponding 8-nitronucleosides derivatives, which were reduced to give the corresponding 8-aminonucleoside derivatives. Debenzoylation of protected nucleosides formed by using methanolic sodium methoxide afforded the
摘要1,3-二甲基黄嘌呤(茶碱),3-苄基黄嘌呤和3-苄基-1-甲基黄嘌呤与1-O-乙酰基-2,3,5-三-O-苯甲酰基-β-D-呋喃呋喃糖的偶联反应相应的被保护的核苷。茶碱和3-苄基-1-甲基黄嘌呤保护的核苷中的每一个的硝化产生相应的8-硝基核苷衍生物,将其还原以得到相应的8-氨基核苷衍生物。通过使用甲醇甲醇钠形成的被保护的核苷进行脱苯甲酰化,分别得到相应的游离N-核苷。已经阐明并报道了产品的结构,并且还筛选了一些产品的抗微生物活性。一些被测产品显示中等活性。图形概要
