Herein, we describe the development of a copper‐catalyzed C(sp3)‐amination of proaromatic dihydroquinazolinones derived from ketones. The reaction is enabled by the intermediacy of open‐shell species arising from homolytic C−C bond‐cleavage driven by aromatization. The protocol is characterized by i...
