Abstract

Procedure for obtaining sulfonated derivatives of erythromycin in the hydroxyl of carbon C4'' of the cladinose ring, characterized in that a compound of general formula II, **(See formula)** where: R1 can be H, aliphatic acyl radicals of 1 to 4 carbon atoms or benzoyl radicals, optionally substituted by alkyloxy radicals, it is reacted at room temperature with a chloride or anhydride of an alkyl or arylsulfonic acid in an anhydrous solvent and, at the same time, it is a scavenger of the hydrochloric acid that is evolved during the reaction, to obtain a compound of general formula I, **(See formula)** where: R can be a C1-4 -alkyl radical or a benzene ring, optionally substituted by alkyl, halogen, nitro, alkyloxy or acetamido radicals, R1 can be H, aliphatic acyl radicals of 1 to 4 carbon atoms or benzoyl radicals, optionally substituted by alkyloxy radicals, and X is an oxygen atom.
