An efficient method for the synthesis of 6-arylpurines (nucleosides) was developed via Suzuki–Miyaura cross-coupling reactions of 6-chloropurines (nucleosides) and sodium tetraarylborate in neat water (ethanol). The process gave good to high isolated yields within a short reaction time under microwave irradiated conditions.
通过在净水(乙醇)中6-氯嘌呤(核苷)和四芳基硼酸钠的Suzuki-Miyaura交叉偶联反应,开发了一种合成6-芳基嘌呤(核苷)的有效方法。该方法在微波辐照条件下,在短的反应时间内获得了良好的高分离收率。
