Cyclic 2-thiomethyl-5-amidofurans possessing tethered p-bonds were prepared by a dimethyl(methylthio) sulfonium tetrafluoroborate (DMTSF) induced cyclization of various amido dithioacetals. Upon heating, these systems undergo an intramolecular 4+2-cycloaddition reaction. The initially formed Diels-A
