A novel protocol for nickel-catalyzed direct sp(2) C-H bond arylation of purines has been developed. This new reaction proceeded efficiently at room temperature using Grignard reagent as the coupling partner within 5 hours in good to high yields. This approach provides a new access to a variety of C8-arylpurines which are potentially of great importance in medicinal chemistry.
已开发了镍催化嘌呤的直接sp(2)CH键芳基化的新协议。使用格氏试剂作为偶联伴侣,该新反应在室温下有效地进行了5个小时,反应良好,收率很高。这种方法提供了对各种C8-芳基嘌呤的新途径,这些C8-芳基嘌呤可能在药物化学中具有重要的意义。
