  developed for the synthesis of 2′-C-methylnucleosides starting from d -glucose and d -ribose. 3-O-benzyl-1,2-O-isopropylidene-3-C-methyl-α- d -allofuranose was prepared in 5 steps from d -glucose and converted into 1,2,3-tri-O-acetyl-2-C-methyl-5-O-p-methylbenzoyl- d -ribofuranose (5), the starting compound for nucleoside synthesis. Compound 5 was also synthesised from 2-C-hydroxymethyl-2,3-O-isopr

  摘要已经开发了从d-葡萄糖和d-核糖开始合成2'-C-甲基核苷的有效通用方法。从d-葡萄糖经5个步骤制备3-O-苄基-1,2-O-异亚丙基-3-C-甲基-α-d-呋喃糖，并将其转化为1,2,3-三-O-乙酰基-2 -C-甲基-5-Op-甲基苯甲酰基-d-核呋喃糖（5），核苷合成的起始化合物。化合物5也由2-C-羟甲基-2,3-O-异亚丙基-5-O-三苯甲基-d-呋喃呋喃糖合成，其由d-核糖经3步制备。在F3CSO3OSiMe3存在下，将5与尿嘧啶，N4-苯甲酰基胞嘧啶和N6-苯甲酰腺嘌呤的双三甲基甲硅烷基衍生物缩合，然后除去保护性酰基，得到相应的2'-C-甲基核苷。
• Synthesis of 2′-C-methyl-branched isonucleosides

  日期：2008.7

  Novel regioisomers of 2'-methyl-branched nucleosides were designed and synthesized to mimic potent anti-viral drugs like Valopicitabine. The short and efficient synthesis of the targets involves a one-pot tosylation/cyclization step that leads to an activated furan scaffold on which the isonucleosides were built.
