Abstract
AbstractAn I2‐promoted oxidative metal‐free [3+2] tandem annulation for the synthesis of multisubstituted imidazoles from amidines and nitroolefins in the presence of base is developed. This transformation represents an I2‐promoted C−N bond formation strategy in a one‐pot protocol without the requirement of any external metals and ligands. It features inexpensive, wide functional group tolerance, as well as insensitive to air and moisture.
