PROCESS FOR PRODUCING OPTICALLY ACTIVE 8-METHOXY-QUINOLONE-CARBOXYLIC ACID DERIVATIVES AND PHARMACEUTICAL COMPOSITIONS CONTAINING THEM
摘要
Optically active 8-methoxyquinolonecarboxylic acids represented by the formula (I) <CHEM> wherein R<1> is lower alkyl have been found to possess potent antibacterial activity against both Gram-negative and Gram-positive bacteria. The compounds may be synthesized from novel optically active intermediates.
