  Oxidative cyclization of N-alkyl-o-methyl-arenesulfonamides to biologically important saccharin derivatives

  摘要：

  Various biologically important saccharin skeletons and their N-alkyl derivatives have been efficiently prepared by chromium(VI) oxide catalyzed H5IO6 oxidation of N-alkyl-o-methyl-arenesulfonamides in acetonitrile. N-tert-Butyl saccharin skeletons were easily prepared by H5IO6-CrO3 oxidation of N-tert-butyl-o-methyl arenesulfonamides in the presence of acetic anhydride. The method that furnished the novel fluoro and trifluoromethyl substituted saccharin skeletons is characterized by two steps, a simple work-up procedure, a single purification and good overall yields from substituted toluene derivatives.

  Brønsted acid-assisted N-alkylation of sulfonamides using ethers as the alkylation reagents

  摘要：

  N-Alkylation of sulfonamides using cyclic ethers as alkylation reagents and Bronsted acid as a catalyst produced pyrrolidine and piperidine derivatives in good yields. When using symmetrical and unsymmetrical ethers as alkylation reagents, mono-N-allcylation of sulfonamides took place to afford the corresponding products. (C) 2013 Elsevier Ltd.
