The present invention relates to novel 4-oximino-1,2,3,4-tetrahydroquinoline derivatives having anti-edema and diuretic effects. More specifically, the present invention relates to the general formula: (In the formula, R represents a straight-chain or branched alkyl group, and X represents a fluorine atom, a chlorine atom, or a bromine atom.) This invention relates to tetrahydroquinoline derivatives. Since gastrointestinal disorders associated with non-steroidal anti-inflammatory drugs, particularly acidic non-steroidal anti-inflammatory drugs, have become a problem, development of neutral or basic anti-inflammatory analgesics that cause less gastrointestinal disorders and have strong effects has progressed actively. It is being As a result of many years of research on the synthesis of tetrahydroquinoline derivatives, the present inventors have discovered a novel 4-oximino-1 compound that exhibits strong anti-edema and diuretic effects and hardly causes gastrointestinal disorders.
They discovered a 2,3,4-tetrahydroquinoline derivative and completed the present invention. The compound of the present invention can generally be produced as follows. That is, p-halogen-substituted aniline and acrylic ester are heated in a solvent such as benzene, toluene, ethyl acetate, or ethanol, or if desired, sodium hydride,
A p-halogen-substituted aniline and an acrylic acid ester are reacted using a base such as sodium alkoxide to obtain a 3-(p-halogen-substituted phenylamino)propionic acid ester. After hydrolyzing the ester of the compound obtained in this way, using phosphorus pentoxide, polyphosphoric acid, etc. as a dehydrating agent, and heating in the presence of a solvent such as benzene, toluene, xylene, etc., or in the absence of a solvent, 6-halogen-substituted-4-oxo-1,2,3,4-tetrahydroquinoline can be synthesized. Alternatively, 3 obtained by reacting p-halogen-substituted aniline with β-propiolactone in the presence of a Lewis acid catalyst such as zinc chloride or aluminum chloride, or in the presence of a solvent such as acetonitrile without a catalyst.
-(p-halogen-substituted phenylamino)propionic acid is ring-closed by dehydration with phosphorus pentoxide, polyphosphoric acid, etc., or if desired, the carboxyl group is converted into acid chloride, and then ring-closed by Friedel-Crafts reaction, 6 -Halogen-substituted-4-oxo-
1,2,3,4-tetrahydroquinoline is obtained (see J. Medicinal. Chem., 8 , 566-571). 6-halogen substituted-4- synthesized in this way
N-alkoxycarbonylation of oxo-1,2,3,4-tetrahydroquinoline involves condensation of various chloroformates with 6-halogen-substituted-4-oxo-1,2,3,4-tetrahydroquinoline, triethylamine, pyridine, etc. It can be obtained by reaction in a solvent such as ether, tetrahydrofuran, dioxane, dichloromethane, chloroform, or benzene in the presence of an organic base. Alternatively, it can be obtained by reacting the various chloroformates described above with an alkali metal amide such as sodium, potassium, or lithium of 6-halogen-substituted-4-oxo-1,2,3,4-tetrahydroquinoline in the aforementioned solvent. . By heating the N-substituted-6-halogen-substituted-4-oxo-1,2,3,4-tetrahydroquinoline derivative synthesized in this manner with hydroxylamine hydrochloride in a mixed solvent of pyridine-alcohol, the present invention N-substituted-6-halogen-substituted-4
-oximino-1,2,3,4-tetrahydroquinoline derivatives can be obtained. The compounds of the present invention obtained in this way can be formulated into pharmaceuticals by suitable conventional methods, alone or together with other pharmaceutically active compounds, and optionally with binders, fillers, fragrances, etc. used in the pharmaceutical industry. It can be converted into a usable product. The present invention will be explained below with reference to Examples. In addition, parts and % in the examples are parts by weight and weight %, respectively.
