Abstract

Procedure for the preparation of new antibiotics of the formula **(See formula)** in which X is taken from the groups made up of **(See formula)** where R1 is taken from the group consisting of hydrogen, lower alkyl, phenyl, and phenyl substituted by a member of the group consisting of halogen, nitro, and lower alkyl; R2 is taken from the group consisting of hydrogen lower alkyl, lower alkanoyl, (see formula), benzoyl and benzoyl substituted by a member of the group consisting of halogen, nitro and lower alkyl; R3 is taken from the group consisting of hydrogen, halogen, nitro, amino, lower alkanoylamino, lower alkylamino, phenylazo and phenylazo substituted by a member of the group consisting of halogen, nitro, lower alkyl and lower alkoxy; and R4 is taken from the group consisting of -OH, = O and = N-OH, provided that at least one of the symbols R1, R2 and R3 is other than hydrogen or R4 is other than = O; dehydration products of the compounds of formula V, in which X represents group (a) and R4 is = O; and of pharmaceutically acceptable salts of those of said compounds which are acidic, procedure comprising subjecting a compound of the formula **(See formula)** or a respective pharmaceutically acceptable salt, in the order of succession desired, to one or more of the following procedural steps; (l) treatment with an esterifying agent to obtain an ester group R1; (2) treatment with a lower alkylating agent, to form a compound of formula V in which R1 and/or R2 are lower alkyl; (3) treatment with an agent giving a member of the lower alkanoyl groups (see formula), benzoyl and benzoyl substituted by a member of the group consisting of halogen, nitro and lower alkyl, to form a compound of formula V in which R2 has the respective meaning; (4) treatment with a halogenating agent, to form a compound of formula V, wherein R3 is halogen; (5) treatment with a nitrating agent, to form a compound of formula V, in which it is nitro; (6) treatment with a diazonic salt of a compound chosen from aniline and aniline substituted by a member of the group consisting of halogen, nitro, lower alkyl and lower alkoxy, to form a compound of formula Y, in which R3 is taking the group consisting of phenylazo and phenylazo substituted by a member taken from the group consisting of halogen, nitro, lower alkyl and lower alkoxy; and (7) treatment with an acid addition salt of the hydroxylamine, to form a compound of formula V, where R4 is hydroxyimino, or reduction to form a compound of formula V where R4 is hydroxy, or treatment with a dehitrating agent to form a respective dehydration product; after which, if desired, a nitro group present is reduced to an amine group or, in the presence of a lower alkyl aldehyde, to a lower alkylamine group; if desired, the thus formed amine group is subjected to lower alkylation or lower alkanzylation or is converted to a diazo group by treatment with nitrous acid or a lower alkyl nitrite; and, if desired, an acid of the formula Y obtained is converted into a respective pharmaceutically acceptable salt.
