The invention relates to novel quinolone derivatives and naphthyridone derivatives which are substituted in the 7-position by a partially hydrogenated isoindolinyl ring, to processes for their preparation and to antibacterial agents and feed additives containing them.
Novel bactericidal pyrido[1,2,3-d,e,][1,3,4]benzoxadiazine derivatives of the formula (I) ##STR1## in which R.sup.1 is hydrogen or C.sub.1 -C.sub.4 -alkyl optionally substituted by hydroxyl or halogen, R.sup.2 independently of R.sup.1 is hydrogen or methyl, R.sup.3 is hydrogen or C.sub.1 -C.sub.4 -alkyl, R.sup.4 is hydrogen, C.sub.1 -C.sub.4 -alkyl optionally substituted by hydroxyl, methoxy, amino, methylamino or dimethylamino, or (5-methyl-2-oxo-1,3-dioxol-4-yl)-methyl, X.sup.1 is hydrogen or halogen and Z is a radical of the structure ##STR2##
The present invention relates to new 8-amino-10-(azabicycloalkyl)-pyrido\x9b1,2,3-d,e!\x9b1,3,4!benzoxadiazine derivatives of the general formula (I) ##STR1## in which the radicals R.sup.1 to R.sup.4, Z and X.sup.1 have the meaning given in the description, processes for their preparation and their use in antibacterial compositions.
