A radical cascade methylation/cyclization of ortho‐cyanoarylacrylamides was developed by utilizing dicumyl peroxide as a methylation reagent. This transformation provides a simple and straightforward approach to methylated quinoline‐2,4(1H,3H)‐diones, and exhibits a wide substrate scope. Furthermore, this reaction could be readily scaled up.
通过使用过氧化二枯基作为甲基化试剂,开发了邻-氰基芳基丙烯酰胺的自由基级联甲基化/环化反应。这种转化为甲基化喹啉-2,4(1 H,3 H)-二酮提供了一种简单明了的方法,并具有广泛的底物范围。此外,该反应可以容易地扩大规模。
