An efficient C-3 sulfuration of oxindoles has been developed. Using disulfide as the sulfurating agent, a wide range of sulfurated oxindoles have been synthesized under t-BuOK/N,N-dimethylformamide (DMF) promoted conditions. The present method is highly atom economic, environmentally friendly and tolerated a broad scope of substrates.

Key words: oxindole, disulfide, sulfuration, radical
