1,3-Benzodithiolium Cation Mediated Cyclization Reactions

Rigby, James H.,Kotnis, Atul,Kramer, James

, p. 5078 - 5088 (2007/10/02)

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.
