摘要：

The 1,4-oxathiine-S-oxides 6 when heated at 60 degrees C in CHCl3 undergo a retro Diels-Alder reaction with generation of alpha,alpha'-dioxosulfine 8. This reactive intermediate can be trapped by electron rich dienophiles as well as by dienes. In both cases the cycloaddition reactions show interesting stereoselective features.
