donor–acceptor (EDA) complex-promoted photoreaction for the synthesis of C2-malonylated indoles. The protocol provides access to a broad range of functionalized indoles in good yields through the coupling reaction of indoles with diethyl bromomalonate under visible-light irradiation without the need for any transition-metal catalyst or photocatalyst.
在此,我们报告了一种基于卤素键的电子供体 - 受体 (EDA) 复合物促进的光反应,用于合成 C2-丙二酰化吲哚。该协议通过吲哚与溴丙二酸二乙酯在可见光照射下的偶联反应,无需任何过渡金属催化剂或光催化剂,即可以良好的收率获得广泛的功能化吲哚。
