Pyridobenzothiazine derivatives with high antimicrobial activity having the following general formula:
wherein
R is H or CH3: n is 0 or 1 or 2 and Y is Cl or F,
wherein R1 is a C1-C6 alkyl
or a C2-C6 alkenyl, or an arylalkyl, arylalkylcarbonyl, alkylcarbonyl, alkyloxycarbonyl, possibly substituted with halogens or hydroxy groups.
The present invention relates also to the processes for obtaining the compounds having the general formula (I). Such processes consist in synthesis routes using as starting products 3-chloro-4-fluoroaniline, or 2,3,4-trifluoronitrobenzene.
具有以下通式的高抗菌活性的吡啶并噻嗪衍生物:
其中
R 是 H 或 CH3:n 是 0 或 1 或 2,Y 是 Cl 或 F、
其中 R1 是 C1-C6 烷基
或 C2-C6 烯基,或可能被卤素或羟基取代的芳烷基、芳烷基羰基、烷基羰基、烷氧基羰基。
本发明还涉及获得通式(I)化合物的工艺。这些工艺包括以 3-氯-4-氟苯胺或 2,3,4-三氟硝基苯为起始产物的合成路线。
