摘要:
7-(1-Pyrrolidinyl)-3-quinolone- and -naphthyridone-carboxylic acid derivatives as antibacterial agents and feed additives, of the formula ##STR1## in which X.sup.1 is halogen,X.sup.2 is hydrogen, halogen, amino or other radical,R.sup.1 is alkyl, cycloalkyl, optionally substituted phenyl or other radical,R.sup.2 is hydrogen, alkyl or a dioxolylmethyl radical,R.sup.3 is ##STR2## and A is N, CH, C-halogen, or the like, or forms a bridge with R.sup.1,and addition products thereof.
摘要:
Process for the preparation of antibacterial compounds of the formula ##STR1## comprises condensing an oxo compound of the formula ##STR2## with an amino compound of the formula ##STR3## to produce a compound of the formula ##STR4## reacting the compound of the formula (III) with a compound of the formula ##STR5## to give a compound of the formula ##STR6## and then eliminating the amino-protective group ##STR7##
摘要:
The invention relates to new 7-(2,7-Diazabicyclo[3.3.0]octyl)-3-quinolone- and -naphthyridonecarboxylic acid derivatives, processes for their preparation, and anti-bacterial agents and feed additives containing them.

摘要:
An antibacterially active quinolone or naphthyridonecarboxylic acid derivative of the formula ##STR1## in which R.sup.1 stands for various organic radical,R.sup.2 stands for hydrogen, alkyl having 1 to 4 carbon atoms or (5-methyl-2-oxo-1,3-dioxol-4-yl)-methyl,R.sup.3 stands for hydrogen or amino,R.sup.4 stands for a radical of the formula ##STR2## A stands for N or C--R.sup.5, whereinR.sup.5 stands for hydrogen, halogen methyl, cyano or nitro or else together with R.sup.1 can form a bridge of the structure ##STR3## or a pharmaceutically utilizable hydrate, acid addition salt, alkali metal salt, alkaline earth metal salt, silver salt or guanidinium salt of the carboxylic acid when R.sup.2 is hydrogen.
