Conclusions

  1. 1.

    1,2-Oxathiolan-5-one-2-oxides are readily cleaved by nucleophiles (H2O, ROH, HNR2) under mild conditions at the O-CO bond only, with the formation of the β-(hydroxysulfinyl)-alkanoic acid derivatives.

  2. 2.

    2,1-Benzoxathiol-3-one-1-oxide is cleaved by alcohols at both the O-CO and the O-SO bonds to give the unstable monoesters at the carboxyl and sulfinyl groups.

  3. 3.

    Unlike 2,1-benzoxathiol-3-one-1-oxide, 1,2-oxathiolan-5-one-2-oxides on boiling with excess alcohols give β-(hydroxysulfinyl)alkanoic acid bisesters.
