and heterocyclic sulfonamides react with phenylacetyl chlorides to produce benzhydryl derivatives in a single step. The reaction proceeds via tandem amide bond formation/Dohmori-Smiles rearrangement under the simple conditions of an aqueous base. In the case of o-nosylamides, a further reaction takes place at the nitro group to yield indazoles.
