A visible-light-induced photoredox Minisci alkylation reaction of N-heteroarenes with ethyl acetate has been reported. The low-toxic ethyl acetate was used for the first time as an alkylation reagent. Hence, 4-quinazolinones, quinolines and pyridines reacted smoothly in the current reaction system. Mechanistic studies indicate that LiBr plays a key role to dramatically improve the efficiency of the
已经报道了 N-杂芳烃与乙酸乙酯的可见光诱导的光氧化还原 Minisci 烷基化反应。首次使用低毒的乙酸乙酯作为烷基化试剂。因此,4-喹唑啉酮类、喹啉类和吡啶类在当前反应体系中反应平稳。机理研究表明,溴化锂通过介导氢原子转移在显着提高反应效率方面发挥着关键作用。
