Direct C–H Cyanoalkylation of Quinoxalin-2(1H)-ones via Radical C–C Bond Cleavage
TL;DR: An efficient synthesis of cyanoalkylated heteroarenes via iron-catalyzed direct C-H cyanoalksylation of heterOarenes has been developed andStructurally diverse cyanoALKyl motifs generated through C-C bond cleavage of cyclobutanone oxime esters have been introduced into quinoxalin-2(1H)-ones, flavone, benzothiazoles, and caffeine in good to excellent yields.
