We have developed a new method for the synthesis of 2-aryl-1-sulfonylpyrrolidines on the basis of reactions between various phenols and N-(4,4-diethoxybutyl)sulfonamides in the presence of trifluoroacetic acid. The structures of the obtained products were confirmed by 1Н and 13С NMR spectroscopy, IR spectroscopy, and X-ray structural analysis.
