for the quinone synthesis. A concise synthesis of novel substituted quinone derivatives from commercially available starting materials was developed. For this synthesis, classical photo-induced 6π-electrocyclization was utilized, followed by oxidative aromatization reaction, and subsequent oxidative coupling reactions in the presence of CuCl(OH)-TMEDA. The unique quinone derivatives were characterized
摘要 从市售原料中合成了新的取代醌衍生物的简明合成方法。对于该合成,利用经典的光诱导的6π-电环化,然后进行氧化芳构化反应,以及随后在CuCl(OH)-TMEDA存在下进行氧化偶联反应。独特的醌衍生物通过IR,1 H和13 C NMR光谱学和质谱数据分析进行表征。在某些情况下,获得了酮二聚体作为醌合成的重要中间体。 从市售原料中合成了新的取代醌衍生物的简明合成方法。对于该合成,利用经典的光诱导的6π-电环化,然后进行氧化芳构化反应,以及随后在CuCl(OH)-TMEDA存在下进行氧化偶联反应。独特的醌衍生物通过IR,1 H和13 C NMR光谱学和质谱数据分析进行表征。在某些情况下,获得了酮二聚体作为醌合成的重要中间体。
