Syntheses of quinolone hydrochloride enantiomers from synthons (R)- and (S)-2-methylpiperazine
摘要:
A series of R and S enantiomers of 7-(3-methylpiperazin-l-yl) quinolone derivatives were synthesized from (R)- and (S)tert-butyl 2-methylpiperazine-l-carboxylate and tested for their antibacterial activities on 14 kinds of bacteria. Although no distinct difference in in vitro antibacterial activities was observed, 2-64-fold difference between R and S enantiomers was observed in approximately 52% of cases. (c) 2005 Elsevier Ltd.
