  7-Azetidinylquinolones as antibacterial agents. Synthesis and structure-activity relationships

  摘要：

  A series of novel antibacterial quinolones and naphthyridones has been prepared which contain 7-azetidinyl substituents in place of the usual piperazine or aminopyrrolidine groups. These azetidinyl derivatives were evaluated for in vitro activity by determining minimum inhibitory concentrations against a variety of bacteria. In vivo efficacy in the mouse infection model and blood levels in the mouse were determined for several compounds. The influence on the structure-activity relationships of varying substituents in the azetidine ring and at position 8 (CH, CF, CCl, N) and N-1 (ethyl, fluoroethyl, cyclopropyl, tert-butyl, 4-fluorophenyl, and 2,4-difluorophenyl) was also studied. Compounds with outstandingly broad-spectrum activity, particularly against Gram-positive organisms, improved in vivo efficacy, and high blood levels were identified in this work. 7-Azetidinyl-8-chloroquinolones were considered as warranting further development.

  6-fluoro-7-substituted-1,4-dihydro-4-oxoquinoline-3-carboxylic acids have been prepared. At the N-1 position "standard" substitution was employed with the ethyl, cyclopropyl, and p-fluorophenyl groups being used. At C-7 the introduction of some novel piperazines was made. Most notably, 2-(fluoromethyl)piperazine (10) and hexahydro-6-fluoro-1H-1,4-diazepine (16, fluorohomopiperazine) at the quinolone C-7 position

  Treatment of methyl propiolate and 2,4,5-trifluoro-, 2-fluoro-, 2-fluoro-5-methoxy- or 2,3,4,5-tetrafluorobenzaldehydes with a ZrCl4/Bu4NI combination induces an aldol reaction to furnish β-iodo-α-(hydroxyalkyl)acrylates. These can be used for the preparation of several quinolone intermediates, 1-substituted 4-oxo-1,4-dihydroquinoline-3-carboxylic acids and 9,10-difluoro-3-methyl-2,3-dihydro-7-oxo-7H-pyrido[1,2,3-de][1,4]benzoxazine-6-carbox­ylic acid through the oxidation, amination and hydrolysis reactions.
