  Synthesis of N-(1-Aziridinyl)-6-fluoro-1,4-dihydro-4-oxoquinoline-3-carboxylic Acids

  摘要：

  A series of N-(1-aziridinyl)quinoline-3-carboxylic acid derivatives (e.g. 11a-f, 20a-g, 21a-d) have been synthesized by insertion reaction of nitrenes (e.g. ethyl 7-chloro-6-fluoro-1-nitreno-1,4-dihydro-4-oxoquinoline-3-carboxylate (9)) into double bond of different olefins (e.g. styrene (10a), see Schemes 2 and 4). The nitrenes were formed in situ by oxidation of N-aminoquinolin-4(1H)-one derivatives (8, 18a,b) using Pb(OAc)(4) as oxidizing agent.

  日期：1996.7

  New racemic N-(1-aziridino)-6-fluoro-7-(4-methylpiperazin-1-yl)-4(1H)-quinolone-3-carboxylic acids (9a-i) were synthesized and their antibacterial activities were tested against Gram-positive and Gramnegative micro-organisms. According to the MIC, all compounds studied are less active than Ciprofloxacin; two of them (9a,b) have similar activity as Nalidixic acid (1). Copyright (C) 1996 Elsevier Science Ltd
