Synthesis of 6H-Benzo[c]chromene Scaffolds from O-Benzylated Phenols through a C–H Sulfenylation/Radical Cyclization Sequence

[Image: see text] S-Aryl dibenzothiophenium salts, obtained through a highly regioselective C–H sulfenylation of o-benzyl-protected phenols, are used as precursors of 6H-benzo[c]chromenes. The reaction starts with a photocatalytically triggered single-electron transfer to the sulfonium salt, which p...
