Abstrakt: Pyrazoloindolones are synthesized from N -tosylhydrazones in a one-pot multistep process which include base-promoted (i) electrocyclization reaction of N -tosylhydrazones derived from α,β-unsaturated aldehydes, (ii) aromatic nucleophilic substitution, and (iii) a domino cyclization–oxidation process under aerobic conditions.
