reported ligand-coupling reactions of Grignard reagents with pyridylsulfonium salts. The method has wide functional group tolerance and enables the formation of bis-heterocycle linkages, including 2,4′-, 2,3′-, and 2,2′-bipyridines, as well as pyridines linked to pyrimidines, pyrazines, isoxazoles, and benzothiophenes. The methodology was successfully applied to the synthesis of the natural products caerulomycin
本文报道了格氏试剂与吡啶基锍盐的配体偶联反应。该方法具有广泛的官能团耐受性,能够形成双杂环键,包括 2,4'-、2,3'-和 2,2'-联吡啶,以及与嘧啶、吡嗪、异恶唑连接的吡啶,和苯并噻吩。该方法成功地应用于天然产物 caerulomycin A 和 E 的合成。
