  Quinolone antimicrobial agents. 1. Versatile new synthesis of 1-alkyl-1,4-dihydro-4-oxo-3-quinolinecarboxylic acids

  摘要：

  A flexible reaction sequence has been developed which starts with readily available anthranilic acids or isatoic anhydrides and leads regiospecifically to 1-alkyl-1,4-dihydro-4-oxo-3-quinolinecarboxylic acids after reaction with 1,3-dicarbonyl compounds. The sequence is superior to earlier published methods by allowing electron-releasing and -withdrawing groups in any position on the aro;atic ring, by allowing convenient substitution at C2, and better overall yield. A number of new and known antimicrobial agents were prepared and tested in vitro, demonstrating, inter alia, that substitution of the H at C2 abolished antibacterial activity.

  the 2-chloro derivative of oxolinic acid, ethyl 1-ethyl-1,4-dihydro-2-hydroxy-6,7-methylenedioxy-4-oxo-3-quinolinecarboxylate was treated with phosphorus oxychloride. The compound obtained was the 4-chloro-2-oxo-quinoline. The structure was confirmed by 13C nmr and mass spectral techniques. The 2-halocarbonitrile was obtained by a Sandmeyer reaction but could not be hydrolysed into the acid.

  为了制备草酸的2-氯衍生物，用氯氧化磷处理1-乙基-1，4-二氢-2-羟基-6，7-亚甲基二氧基-4-氧代-3-喹啉羧酸乙酯。得到的化合物是4-氯-2-氧代-喹啉。通过13 C nmr和质谱技术证实了该结构。通过桑德迈尔反应获得了2-卤代腈，但是不能被水解成酸。
