Asymmetric synthesis and properties of the enantiomers of the antibacterial agent 7-(3-aminopyrrolidin-1-yl)-1-(2,4-difluorophenyl)-1,4-dihydro-6-fluoro-4-oxo-1,8-naphthyridine-3-carboxylic acid hydrochloride

quinolonecarboxylic acid class of antibacterial agents and is currently undergoing clinical evaluation. We have developed efficient asymmetric syntheses of the enantiomers of this agent. The S-(+) enantiomer 1a is 1-2 log2 dilutions more active than the R-(-) enantiomer 1b against aerobic bacteria and 1-2 or more log2 dilutions more active against anaerobic bacteria in vitro. The enantiomer 1a shows
