Palladium‐Catalyzed Double CH Activation Directed by Sulfoxides in the Synthesis of Dibenzothiophenes

Abstract

SO shows where to go: A novel double CH activation of aromatic compounds with a sulfoxide as a directing group results in the highly regioselective synthesis of polysubstituted dibenzothiophenes (see scheme). The reaction cascade consists of palladium-catalyzed double CH activation and a Pummerer rearrangement followed by palladium-catalyzed CS bond formation.
