Ruthenium-Catalyzed Hydroarylation and One-Pot Twofold Unsymmetrical C—H Functionalization of Arenes.

Methyl phenyl sulfoximine is used as a directing group in the ruthenium-catalyzed intramolecular hydroarylation of alkene-tethered benzoic acid derivatives to afford dihydrobenzofurans and indolines.
