A general, efficient, and experimentally simple one‐pot new method for the synthesis of cyclic imines throughintramolecularcyclization of brominated oxime ether promoted by ytterbium(0) was reported for the first time. In this new strategy for the construction of cyclic imines, the N–O bond is used as a receptor of ytterbium reagent rather than as a source of N‐centred radical.
