A visible-light-induced radical tandem cyclization/arylation between 2-amino-1, 4-naphthoquinone and N-allyl-2-bromo-2,2-difluoroacetamides has been developed without an external photocatalyst. The transformation could be carried out at room temperature and gave a variety of C-3-functionalized 2-amino-1,4-naphthoquinone derivatives in moderate to excellent yields. Moreover, mechanistic studies revealed
已经开发了在没有外部光催化剂的情况下在2-氨基-1、4-萘醌和N-烯丙基-2-溴-2,2-二氟乙酰胺之间的可见光诱导的自由基串联环化/芳基化。该转化可以在室温下进行,并以中等至优异的产率得到各种C-3-官能化的2-氨基-1,4-萘醌衍生物。此外,机理研究表明,反应是由电子供体-受体(EDA)配合物的形成驱动的。
