The synthesis of a large group of benzenesulfonamides containing both a primary and secondary sulfonamide moiety is described. These compounds are powerful inhibitors of several isozymes of the enzyme carbonic anhydrase. Separate QSAR's are given for inhibition of three of these isozymes, using descriptors mainly derived from molecular orbital calculations by the semiempirical AM1 method. Activity was found to depend on electrostatic potential-based charges on the atoms of both sulfonamide groups, HOMO and LUMO energies, dipole moments, and lipophilicities. These results are compared with those from other studies. (C) Elsevier, Paris.

Ferric Chloride-Mediated Transacylation of <i>N</i>-Acylsulfonamides
Transacylation of N-acylsulfonamides, which replaces the N-acyl group with a new one, is a challenging and underdeveloped fundamental transformation. Herein, a general method for transacylation of N-acylsulfonamides is presented. The transformation is enabled by coincident catalytic reactivities of FeCl3 for nonhydrolytic deacylation of N-acylsulfonamides and subsequent acylation of the resultant sulfonamides
