An efficient tandem cyclizationâacetoxylation of o-acyl anilines mediated by the combination of iodobenzene diacetate with tetrabutylammonium iodide provides a new convenient and useful route to 2-acetoxy indolin-3-ones, which are ready to be converted into other 2-substituted 3-oxyindole derivatives.
