Using tandem imine formation and (diastereoselective) reductive cyclization reactions via iron- or manganese-catalyzed hydrogen-atom transfer, unsaturated amines (olefin-amine reagents, OLA) such as I, II, and III yielded spirocyclic, bridged, and fused saturated nitrogen heterocycles such as IV, V, and VI. A mechanism is proposed using a metal hydride hydrogen atom transfer to generate a C-centered radical that undergoes addition to an unactivated imine, leading to an N-centered radical; regeneration of the metal catalyst by O2 and a second HAT to form the unprotected saturated N-heterocycle yields the observed products.
