A short route to a series of 2′-deoxy-C-nucleosides featuring substituted nucleobases has been developed. The key step is the formation of the cyclized products following Mukaiyama's type amide coupling and a simple dehydration, starting from readily accessible synthons. The epimerization of the C1′-stereogenic center was avoided under mild and controlled conditions.
的一系列2'-脱氧阿短路线Ç核苷设有取代的核碱基得到了发展。关键步骤是在Mukaiyama类型的酰胺偶联作用和简单的脱水作用之后,从容易获得的合成子开始,形成环化产物。在温和且受控的条件下避免了C1'-立体异构中心的差向异构。
