Abstract
A method for the preparation of previously difficult to access heterofunctional 3,3'-sulfonyldibenzoic acid derivatives containing amino-, alkylamino-, hydroxy-, and alkoxy substituents at the vicinal position relative to the sulfonyl group has been elaborated. The interaction of methyl 4-nitro-10,10-dioxophenoxathiine-2,8-dicarboxylate with amines and O-nucleophiles was shown to proceed under mild conditions, resulting in oxathiine ring opening, and the nucleophilic substitution occurred exclusively at position 4а of phenoxathiine.
