摘要
通过区域选择性级联自由基环化，开发出一种高效、无过渡金属和光的多杂环方法。该氧化还原中性方案具有广泛的底物范围和良好的官能团耐受性，并可能经历一个 SET 过程，该过程由催化量的醌与 2.0 等量的 Cs2CO3 共同启动。
Metal- and light-free approach to polyheterocycles via a quinone-Cs2CO3 couple promoted regioselective cascade radical cyclization
A highly efficient, transition-metal- and light-free approach to polyheterocycles via regioselective cascade radical cyclization is developed. The redox-neutral protocol has a broad substrate scope with good functional group tolerance and probably undergoes a SET process, which is initiated by catalytic amounts of quinone in combination with 2.0 equiv. of Cs2CO3.
