Synthesis, characterization, and reactivity of novel 6H-1,3,5-oxathiazine S,S-dioxides

A series of novel 6H-1,3,5-oxathiazine S,S-dioxides were synthesized by the m-CPBA oxidation (2.2 equiv) of 6H-1,3,5-oxathizines. The synthetic utilities of the newly synthesized cyclic sulfones were investigated. In a thermal condition, compounds 6H-1,3,5-oxathiazine S,S-dioxides were found relatively stable, but Lewis acid-induced thermal reaction afforded the corresponding amides. The plausible pathway to amides from 6H-1,3,5-oxathiazine S,S-dioxides was also discussed in this account.

Novel generation and ring closure of 1,3-thiaza-1,3-butadiene S-oxides through thermal cycloreversion of 6H-1,3,5-oxathiazine S-oxides

Heating of 6H-1,3,5-oxathiazine S-oxides efficiently afforded 1,2,4-oxathiazoles through the mechanism involving thermal cycloreversion of the substrates and the subsequent ring closure of the intermediary 1,3-thiaza-1,3-butadiene S-oxides.
