Gold superacid-catalyzed preparation of benzo[c]thiophenesElectronic supplementary information (ESI) available: Synthetic procedures, characterization data and copies of the NMR-spectra. See DOI: 10.1039/c4cc07989b

A three-step synthesis of benzo[ c ]thiophenes is presented in which the key transformation is the gold-catalyzed 5- exo-dig migratory cycloisomerization of a diallyl thioacetal. It was shown that a small amount of in situ generated HAuCl 4 from AuCl 3 is the active catalytic species. A mechanism wa...
