An efficient one‐pot method for the synthesis of various C6‐alkylthio‐substituted purine nucleosides has been developed under microwave irradiation with good to excellent yields without any metal catalyst (see scheme). This process expands the scope of existing synthetic methodologies and was further successfully applied for synthesis of the biologically important compound 4‐nitrobenzylthioinosine
在微波辐射下,开发了一种高效的一锅法合成各种C6-烷硫基取代的嘌呤核苷的方法,其收率好至极好,而且没有任何金属催化剂(参见方案)。该方法扩大了现有合成方法的范围,并进一步成功地用于生物学上重要的化合物4-硝基苄基硫代肌苷(NBTI)的合成。
