Following our previous results on an environmentally benign one-pot Sonogashira-cyclization protocol to obtain substituted furopyrimidine nucleosides under aqueous conditions, we investigate herein the Suzuki-Miyaura cross-coupling reactions of aryl and heteroaryl derivatives at the C5 position of unprotected 2'-deoxyuridine in the same media with a common catalyst system avoiding exotic ligands, since palladium acetate and triphenylphosphine afforded the expected products in moderate to good yields.
                                    继我们之前在
水溶液条件下通过无害环境的一锅 Sonogashira-环化方案获得取代的
呋喃嘧啶核苷的研究成果之后,我们在此研究了在相同介质中使用普通催化剂体系,避免使用外来
配体,在未受保护的 
2'-脱氧尿苷的 C5 位上进行芳基和杂芳基衍
生物的 Suzuki-Miyaura 交叉偶联反应,因为
醋酸钯和
三苯基膦能以中等至良好的收率提供预期产物。
