The synthesis of stable guanofosfocin analogues has attracted considerable attention in the past 15 years. Several guanofosfocin analogues mimicking the three constitutional elements of mannose, ribose, and guanine were designed and synthesized. Interest in ether-linked pseudodisaccharides and 8-alkylated guanines is increasing, due to their potential applications in life science. In this article,
在过去的 15 年中,稳定鸟磷焦素类似物的合成引起了相当大的关注。设计并合成了几种模拟甘露糖、核糖和鸟嘌呤三种构成元素的鸟磷焦素类似物。由于它们在生命科学中的潜在应用,对醚连接的假二糖和 8-烷基化鸟嘌呤的兴趣正在增加。在这篇文章中,一种新的鸟磷焦素类似物 6,一种醚连接的假二糖,α-C-糖苷连接到 8-烷基化鸟嘌呤,从已知的二醇 13 以 10 长的线性步骤序列合成,总产率为 26 %。关键步骤包括环硫酸盐 8 由 7 生成的醇盐开环和 4-N-酰基-2,4-二氨基-5-亚硝基嘧啶 19 的还原环化反应形成化合物 6。
