aryl and indole boronates has been explored in good to excellent yields. In situ generation of nano-Cu2O from CuCl2 under the reaction conditions has been discovered for the first time. The generality of the reaction was further demonstrated by the arylation of 5-iodopyrimidine, iodopyridines, iodobenzenes, and diiodobenzenes and resulted in good to moderate yields. Moreover, bisindole alkaloid Scalaridine
已经研究了无配体铜催化3,5-二碘吡啶与芳基和吲哚硼酸酯的Suzuki-Miyaura偶联,收率良好。原位生成的纳米铜的2从氯化亚铜ø 2在反应条件下已经发现首次。通过5-碘嘧啶,碘吡啶,碘苯和二碘苯的芳基化进一步证明了反应的一般性,并产生了良好至中等的收率。此外,双吲哚生物碱Scalaridine A已成功地以60%的总收率合成。
