  The invention relates to a novel preparation of 3-fluoroquinolines of formula (I) in which R 1 , R 2 , R 3 and R 4 represent: a) a fluorine; b) an alkyl optionally substituted with one to three fluorines, with OR 5 in which R 5 is an alkyl, a hydrogen or a hydroxyl-protecting group, or with NR′R″ in which R′ and R″ represent an alkyl, a hydrogen or an amino-protecting group; c) OR 6 in which R 6 represents a hydrogen, a phenol-protecting group or an alkyl, optionally substituted with a fluorine, with OR 5 or with NR′R″ as defined above; d) NR′ 1 R″ 1 in which R′ 1 and R″ 1 have the values of R′ et R″ or represent an alkyl substituted with a fluorine, with OR 5 or NR′R″ as defined above; e) CO 2 R a , in which R a represents hydrogen, alkyl or a carboxyl-protecting group, and also novel intermediate compounds. The quinolines of formula (I) are intermediates useful in the preparation of compounds having antibacterial activity, described in particular in applications WO 02/40474 or WO 02/72572.

  本发明涉及一种3-氟喹诺酮的新型制备方法，其中R1、R2、R3和R4表示： a）氟； b）一种烷基，该烷基可选择地被一到三个氟原子，OR5（其中R5表示烷基、氢或羟基保护基）或NR′R″（其中R′和R″表示烷基、氢或氨基保护基）所取代； c）OR6（其中R6表示氢、酚保护基或烷基，可选择地被氟原子、OR5或NR′R″所取代）； d）NR′1R″1（其中R′1和R″1具有R′和R″的值或表示被氟原子取代的烷基，可选择地与OR5或NR′R″所定义的基团相结合）； e）CO2Ra（其中Ra表示氢、烷基或羧基保护基），以及新型中间体化合物。式（I）的喹诺酮是一种中间体，可用于制备具有抗菌活性的化合物，特别是在WO 02/40474或WO 02/72572中描述的应用中。
