Intramolecular Aromatic Substitution with Bisthiocarbocations. Variations of Lewis Acid, Solvent and Orthothio Substituents

The effects of Lewis acid, solvent and orthothio substituent have been examined with regard to intramolecular electrophilic aromatic substitution (annulation) with bisthiocarbocations.A suspension of silver trifluoromethanesulfonate in dichloromethane, creating bis(arylthio)carbocations, was found to be the most effective for annulation of six-membered rings.

1,3-Benzodithiolium Cation Mediated Cyclization Reactions

General protocols for the construction of various ring systems employing cation olefin cyclizations initiated by the readily accessible 1,3-benzodithiolium ion are described.Several substituted tetralones and tetralins can be rapidly assembled by this methodology as can a variety of substituted bicyclooctane and tricyclic ring systems.The products of these transformations are amenable to interconversion into a range of functionalized species.
