Smiles rearrangement, an organic intramolecular nucleophilic aromatic substitution reaction, provides a powerful access to the
synthesis of a variety of heterocyclic compounds. In contrast with the conventional protocols for the preparation of complex molecular
structures, Smiles rearrangement, through the conversion of an easily-synthesized precursor into a desired “difficult-to-make’’ product,
presents to be an extremely useful tool in organic synthesis. In the reactions, the yields of the Smiles rearrangement are profoundly influenced
by electronic effect, steric effect and even the pH value. In this review, the detailed preparations of numerous molecules by taking
advantage of Smiles rearrangement are discussed.
