  Synthesis, absolute configuration and intermediates of 9-fluoro-6,7-dihydro-5-methyl-1-oxo-1H,5H-benzo[i,j]quinolizine-2-carboxylic acid (flumequine)

  摘要：

  The antibacterial agent 9-fluoro-6,7-dihydro-5-methyl- 1-oxo- 1H,5H-benzo[iJ]quinolizine-2-carboxylic acid (flumequine) was synthesized in optically active form from 6-fluoro-2-methyl-1,2,3,4-tetrahydroquinoline (FTHQ). Racemic FTHQ was resolved with the enantiomers of 3-bromocamphor-8-sulfonic acid. The configurations were established by X-ray structures of the two diastereoisomeric salts. Enantiomeric excesses were determined by H-1 NMR analysis. (C) 1999 Elsevier Science Ltd. All rights reserved.
