An N-heterocyclic carbene catalyzed remote C(sp3)−H acylation of amides was developed, and also combined with a cascade cyclization. Over 120 functionalized δ-amino ketones and isoquinolinones with diverse substituents were synthesized in up to 99 % yield under mild conditions. Preliminary mechanistic investigations shed light on the organocatalytic radical reaction mechanism.
