This invention relates to processes for producing a 7-isoindoline-quinolonecarboxylic acid derivative represented by the general formula [1] which is useful as an antibacterial agent, and an intermediate thereof:
wherein R1 represents a hydrogen atom or a carboxyl-protecting group; R2 represents a substituted or unsubstituted alkyl, alkenyl, cycloalkyl, aryl or heterocyclic group; R3 represents at least one group selected from hydrogen atom, halogen atoms, substituted or unsubstituted alkyl, alkenyl, cycloalkyl, aryl, alkoxy or alkylthio groups, nitro group, cyano group, acyl groups, protected or unprotected hydroxyl groups and protected or unprotected or substituted or unsubstituted amino groups; R4 represents at least one group selected from hydrogen atom, halogen atoms, substituted or unsubstituted alkyl, alkenyl, cycloalkyl, aralkyl, aryl, alkoxy or alkylthio groups, protected or unprotected hydroxyl or imino groups, protected or unprotected or substituted or unsubstituted amino groups, alkylidene groups, oxo group and groups each forming a cycloalkane group together with the carbon atom to which R4 bonds; R5 represents a hydrogen atom, an amino-protecting group, a substituted or unsubstituted alkyl, cycloalkyl, alkylsulfonyl, arylsulfonyl, acyl or aryl group; R6 represents a hydrogen atom, a halogen atom, a substituted or unsubstituted alkyl, alkoxy or alkylthio group, a protected or unprotected hydroxyl or amino group or a nitro group; and A represents CH or C-R7 in which R7 represents a halogen atom, a substituted or unsubstituted alkyl, alkoxy or alkylthio group or a protected or unprotected hydroxyl group, and to a salt of a 7-isoindoline-quinolonecarboxylic acid represented by the general formula [1], a hydrate thereof and a composition comprising them as an active ingredient.
本发明涉及生产由通式[1]表示的可用作抗菌剂的7-异吲哚啉-喹啉羧酸衍生物及其中间体的工艺:
其中 R1 代表氢原子或羧基保护基团;R2 代表取代或未取代的烷基、烯基、环烷基、芳基或杂环基团;R3 代表至少一个选自氢原子、卤素原子、取代或未取代的烷基、烯基、环烷基、芳基、烷氧基或硫代烷基、硝基、氰基、酰基、受保护或未受保护的羟基和受保护或未受保护或取代或未取代的氨基的基团;R4 代表至少一个选自氢原子、卤素原子、取代或未取代的烷基、烯基、环烷基、芳基、烷氧基或烷硫基、受保护或未受保护的羟基或亚氨基、受保护或未受保护的或取代或未取代的氨基、亚烷基、氧代基团和与 R4 键合的碳原子一起形成环烷基团的基团的基团;R5 代表氢原子、氨基保护基团、取代或未取代的烷基、环烷基、烷基磺酰基、芳基磺酰基、酰基或芳基; R6 代表氢原子、卤素原子、取代或未取代的烷基、烷氧基或硫代烷基、受保护或未受保护的羟基或氨基或硝基;和 A 代表 CH 或 C-R7,其中 R7 代表卤素原子、取代或未取代的烷基、烷氧基或烷硫基或受保护或未受保护的羟基,以及通式[1]代表的 7-异吲哚啉-喹啉羧酸的盐、其水合物和包含它们作为活性成分的组合物。
