Abstract (EN): The chlorosulfonation of flavone and 4'-methoxyflavone with chlorosulfonic acid occurs regioselectively in ring B. The chlorosulfonyl flavones were converted into their corresponding sulfonamides and sulfonates by reaction with alkylamines, anilines, isopropyl alcohol and p-chlorophenol. Two-dimensional (COSY and HETCOR) and one-dimensional selective INEPT experiments were carried out in order to unequivocally assign all the signals in the NMR spectra of compounds.
