A novel route to 4-aryl-5,6-dihydro-1,2-oxathiin-2,2-dioxides and related heterocyclic systems

The addition of a tri n-butylstannyl radical to arene and heteroarene sulfonate esters of homopropargyl alcohol triggers a sequence of [1,6] ipso-substitution followed by 6-endo addition and elimination to yield unusual 4-aryl-5,6-dihydro-1,2-oxathiin-2,2-dioxides and related heterocyclic systems.
