, p. 5078 - 5088 (1990)
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.
SYNTHESIS OF BICYCLOOCTANES BY A TANDEM DIELS-ALDER-CARBOCATION CYCLIZATION STRATEGY
Rigby, James H.,Kotnis, Atul S.
, p. 4943 - 4946 (2007/10/02)
The bicyclooctane ring system is assembled by a three-step process featuring a thermally induced cycloaddition followed by a 1,3-benzothiolium ion mediated cyclization onto an enol or silyl enol ether double bond.
