    • A process of preparing a quinolone carboxylic acid or its derivatives having Formula I, Ia, or IV, as shown herein, comprises using a starting quinolone that already has one or more desired substituents at one or more particular positions on the quinolone ring and preserving the orientation of such substituents throughout the synthesis. The present process comprises fewer steps than prior-art processes. The present process also can include a simple separation of a desired enantiomer of the quinolone carboxylic acid or its derivatives from the enantiomeric mixture. Pharmaceutical compositions comprising fluoroquinolones prepared by the present process can be used effectively against a variety of microbial pathogens.
    • 如本文所示,制备具有式I,Ia或IV的喹诺酮羧酸或其衍生物的方法包括使用在喹诺酮环上的一个或多个特定位置已经具有一个或多个所需取代基的起始喹诺酮,并保留 这些取代基在整个合成过程中的取向。 本方法包括比现有技术方法更少的步骤。 本方法还可以包括从对映异构体混合物中简单分离喹诺酮羧酸或其衍生物的所需对映异构体。 包含通过本方法制备的氟喹诺酮类的药物组合物可以有效地用于各种微生物病原体。
