carboxylation/arylation of indole-tethered unactivated alkenes with CO2 to access various carboxylated indole-fused heterocycles. This reaction is initiated by the addition of a CO2 radical anion to the alkene motif toward an alkyl carbon radical, followed by its addition to the aromatic ring, and then rearomatization to afford the final products. This reaction provides a facile and sustainable protocol for
这里描述的是可见光促进的吲哚系链未活化烯烃与CO 2的级联羧化/芳基化,以获得各种羧化吲哚稠合杂环。该反应通过将CO 2自由基阴离子加成到烷基碳自由基的烯烃基序上引发,随后将其加成到芳环上,然后再芳构化以提供最终产物。该反应为使用CO 2作为羧基源构建羧化吲哚稠合杂环提供了简便且可持续的方案。
