Herein, we report the first protocol for visible-light-induced radical isocyanide insertion reactions between 3-(2-isocyanobenzyl)-indoles and bromodifluoroacetates or bromodifluoroacetamides. The protocol, which has good functional group tolerance and a broad substrate scope, constitutes an efficient and general route to difluoromethylated spiro[indole-3,3'-quinoline] derivatives.
在此，我们报告了首例可见光诱导的自由基异氰化物插入反应，涉及 3-(2-异氰基苄基)-吲哚与溴代二氟乙酸酯或溴代二氟乙酰胺。该方案具有良好的官能团耐受性和广泛的底物范围，是一种高效、通用的合成二氟甲基化螺[吲哚-3,3'-喹啉]衍生物的方法。
