effect the intramolecular oxidative coupling of substituted 4-hydroxyphenyl-N-phenylbenzamides. The transformations could be realized in a catalytic manner by using iodobenzene as catalyst and m-chloroperoxybenzoic acid or urea˙H2O2 as terminal oxidant. This reaction constitutes an efficient method for the synthesis of spirooxindoles. hypervalent iodine - oxidative coupling - phenolic coupling - spirooxindoles
