The Suzuki-Miyaura reaction of 9-unsubstituted 2-, 6-, and 8-halopurine bases with diverse aryl- and alkenylboronic acids in water-acetonitrile mixtures under microwave irradiation was used for the single-step synthesis of arylpurines. In most cases the product crystallized directly from the reaction mixture in high yields and good purity. The scope and limitations of these reactions were studied.
通过水-乙腈混合物中微波辐照下,9-未取代的2-、6-和8-卤代嘌呤碱与多种芳基和烯基硼酸的Suzuki-Miyaura反应,实现了单步合成芳基嘌呤。在大多数情况下,产物以高产率直接从反应混合物中结晶,纯度良好。研究了这些反应的范围和局限性。
