The Mannich reaction is a three-component reaction for preparing alkylamines, but the nucleophilic components rely on C(sp2)−H and activated C(sp3)−H bonds. Here, the authors report an unprecedented multicomponent double Mannich alkylamination for both C(sp2)−H and unactivated benzylic C(sp3)−H bonds.
