We have proposed a mechanism, supported by density functional theory (DFT) calculations, where a hydrogen radical-shuttle (HRS) process explains the chemical and stereochemical results. This work demonstrates the efficient stereoselective synthesis of structurally unique, highly functionalized nitrogen heterocyclic systems using simple protocols and affordable starting materials.
