A novel synthetic approach to benzo[d]isothiazole 1,1-diones having a secondary alkyl substituent at the 3-position
A novel method for the synthesis of benzo[d]isothiazole 1,1-diones with a secondary alkyl substituent at the 3-position is described. Treatment of N-tert-butylbenzenesulfonamide (1) with an excess of BuLi, followed by the reaction with methyl 2-arylpropanoate, gave the corresponding ortho-functionalized benzenesulfonamides 2a-d, which underwent cyclization under TMSCl-NaI-MeCN reflux conditions to afford 3-substituted benzo[d]isothiazole 1,1-diones 3a-d.
