An iron-catalyzed intermolecular [4 + 2] cyclization of arylnitrones with geminal-substituted vinyl acetates was developed for the synthesis of 2,4-disubstituted quinolines in moderate to good yields with good functional group compatibilities. Preliminary mechanistic studies suggest a plausible iron-catalyzed C-H activation process under external-oxidant-free conditions.
一种铁催化的芳基硝酮与偕二取代的乙烯基乙酸酯的分子间[4 + 2]环化反应被开发出来,用于中等至良好收率合成 2,4-二取代的喹啉,具有良好的官能团兼容性。初步的机理研究表明,在外源氧化剂不存在的条件下,可能存在铁催化的 C-H 活化过程。
