Abstract

NEW MATERIAL:A 3-sulforifamycin SV of formula I: (X is acetyl group or H) or 25-deacetyl-3-sulforifamycin SV and their salt.
USE: Antibacterials or intermediates for their synthesis. The introduction of sulfite ions at the 3-position activates and makes the compound useful for the synthesis of 3-iminomethylrifamycin derivatives.
PROCESS: Rifamycin S of formula II or its 25-deacetyl derivative is reacted with a hydrogensulfite or sulfite in a solvent, e.g. dioxane or pyridine, under weakly alkaline conditions at room temperature to 30°C to give the objective compound of formula I. The hydrogensulfite or sulfite is used in an amount 15W20 times the molar amount of the starting material.
