Abstract Sulphuric acid–catalyzed chloralhydrate condensation with different m‐substituted benzoic acids formed trichlorophthalides 1, from which Zn+AcOH reduction afforded various dichloro derivatives 2. These derivatives 2 on treatment with alkaline Hg(OAc)2+I2 furnished different substituted isocoumarins 4.

We are seeking to discover potent CNS-active sulfonylureas with structural features that allow for the formation of several types of prodrugs. We report herein the syntheses of compounds comprising an initial series of hydroxyl-substituted analogues of the potent ATP-sensitive potassium channel blockers glyburide (glibenclamide) and gliquidone. Somewhat unexpectedly, several of the compounds were found to be comparably potent to glyburide as inhibitors of specific [H-3]glyburide binding in rat brain preparations.
