Abstract
alpha-Oxothioaldehyde S-oxides 4a-f can be generated under very mild c onditions from the corresponding sulfinyl compounds 3a-f, which in tur n are obtained by m-chloroperoxybenzoic acid (MCPBA) oxidation of alph a-oxothiophthalimides 2a-f. The reactive sulfine intermediates can be trapped as electron-poor dienophiles as well as electron-poor dienes w ith formation of dihydrothiopyran S-oxides 5a-e or 1,4-oxathiin S-oxid es 6a-f, respectively.
