Benzo-heterocyclic compounds of the formula:
wherein R1 is a lower alkyl group; R2 is a halogen atom or a group of the formula:
(wherein R4 and R5 combine together with the nitrogen atom to which they bind to form a 5- or 6-membered saturated heterocyclic group which may optionally contain an oxygen atom or nitrogen atom within the ring as an additional hetero atom and may also optionally have a substituent selected from a lower alkyl or hydroxy group on the hetero ring): R3 is an amino or nitro group; X is a halogen atom; and n is an integer of 1 or 2, and a salt thereof, which have excellent antimicrobial activities and are useful as an antimicrobial agent, or as an intermediate for the preparation of an active compound.
式中 R1 为低级烷基;R2 为卤素原子或式中的基团(其中 R4 和 R5 与它们结合的氮原子结合在一起形成 5 或 6 元饱和杂环基团,该杂环基团可以选择性地在环内含有一个氧原子或氮原子作为额外的杂原子,也可以选择性地在杂环上具有选自低级烷基或羟基的取代基):R3 为氨基或硝基;X 为卤素原子;n 为 1 或 2 的整数,以及它们的盐,这些化合物具有优异的抗菌活性,可用作抗菌剂或制备活性化合物的中间体。
