A Comparative Study of the Effect of Water and Organic Solvents on 1,3-Dipolar Cycloaddition Reactions of Mesitonitrile Oxide with C-Sulfonyl- and Sulfanyl-Dithioformates

Abstract

1,3-Dipolar cycloadditions of the C-sulfonylated- and sulfanylated-dithioformates with mesitonitrile oxide occurred smoothly in organic and aqueous media to afford 1,4,2-oxathiazoles in good yields. The structures of these cycloadducts have been established via the analysis of NMR data and elemental analyses.
