    摘要: As new compounds are provided 9,3",4"-trialkanoyl SF-837 M.sub.1 substances which have therapeutically useful antibacterial activity and do not show any objectionable long-lasting bitter taste upon its oral administration. These 9,3",4"-trialkanoyl SF-837 M.sub.1 substances may be prepared from SF-837 substance, 9,2',3"-tri-acetyl SF-837 M.sub.1 substance, 9,2'-di-acetyl SF-837 substance, 9-propionyl SF-837 substance or 9,2'-dipropionyl SF-837 substance by acylating the latter with an alkanoic acid anhydride at 50.degree.-120.degree. C to produce the corresponding 9,2',3",4"-tetra-alkanoyl SF-837 M.sub.1 substance and occasionally the 9,18,2',3",4"-penta-alkanoyl SF-837 M.sub.1 substance, with involving the shift of the 4"-alkanoyl group to the 3"-hydroxyl group. Partial and selective hydrolysis of the 9,2',3",4"-tetra-alkanoyl SF-837 M.sub.1 substance and/or the 9,18,2',3",4"-penta-alkanoyl SF-837 M.sub.1 substance so produced gives the desired 9,3",4"-tri-alkanoyl SF-837 M.sub.1 substance.
