Abstract
Title acids of formula (I) (where R is lower alkyl, X is O, S, NH or NCH3, Y is H, F, Cl, Br or CH3, and Z1 and Z2 are H, F, Cl, Br, lower alkyl or alkoxy) and their salts with org. or inorg. bases, are prepd. by eliminating the alkylsulphonyl gp. from a cpd. of formula I; (where R-C(=CH2) is RCH(CH2SO2R2), R2 is lower alkyl) by boiling in a hydroxylic solvent in the presence of a weak base, and opt. converting the reaction prod. into a salt with an org. or inorg. base.
Description
Die vorliegende Erfindung betrifft ein Verfahren zur Herstellung von neuen heterocyclischen Carbonsäuren.
Heterocyclische Carbonsäuren der Formel I,
EMI1.1
in welcher
R eine niedere Alkylgruppe,
X Sauerstoff. Schwefel, die Iminogruppe oder die Methyliminogruppe,
Y Wasserstoff. Halogen bis Atomnummer 35 oder die Methylgruppe und
Z1 sowie Z2 Wasserstoff, Halogen bis Atomnummer 35, eine niedere Alkyl- oder Alkoxygruppe bedeuten, sowie ihre Salze mit anorganischen oder organischen Basen, sind bisher nicht bekanntgeworden.
Wie nun gefunden wurde, besitzen die neuen Verbindungen wertvolle pharmakologische Eigenschaften. Sie zeigen diuretische und saluretische Wirkung. Diese Eigenschaften kennzeichnen diese Verbindungen als geeignet zur Behandlung von Störungen, welche durch mangelhafte Ausscheidung von Elektrolyten, insbesondere von Natriumchlorid, bedingt sind. Solche Störungen sind die Ursache von Öde- men und Hypertonien. Diese Verbindungen, z. B. die 4-Chlor5-(2-methylen-butyryl)-indol-2-carbonsäure, die 6-Methoxy 5-(2 -methylen-butyryl)-benzofuran-2-carbonsäure und die 6 -Methyl-5 -(2-methylen-butyryl) -benzofuran-2-carbonsäure vermögen am Hund und am Kaninchen bei einer Dosierung von 10 mg/kg p.o. die Harnausscheidung sowie die Ausscheidung der Natriumionen und der Chlorionen beträchtlich zu erhöhen.
In den heterocyclischen Carbonsäuren der Formel I nimmt Zl die 4- oder 6-Stellung und Z2 die 6- oder 7-Stellung ein.
R, Z1 und Z2 bedeuten als niedere Alkylgruppen beispielsweise die Methyl-, Äthyl-, Propyl-, Isopropyl-, Butyl- oder die tert.-Butylgruppe und Zj sowie Z2 als niedere Alkoxygruppen beispielsweise die Methoxy-, Äthoxy-, Propoxy-, Isopropoxy-. Butoxy- oder die sek.-Butoxygruppe.
Nach dem erfindungsgemässen Verfahren stellt man die Verbindungen der Formel I her, indem man einer Verbindung der Formel II
EMI1.2
in welcher R, X, Y, Z1 und Z2 die unter Formel I angegebene Bedeutung haben und R2 eine niedere Alkylgruppe bedeutet, durch Kochen in einem hydroxylhaltigen Lösungsmittel in Gegenwart einer schwachen Base die Alkylsulfongruppe abspaltet.
Als schwache Basen kommen Natriumacetat oder Natriumhydrogencarbonatlösungen in Frage, und als Lösungsmittel kann Wasser oder eine niedere Fettsäure verwendet werden.
Die Verbindungen der Formel II können in einfacher Weise hergestellt werden, indem man eine Verbindung der Formel III
EMI1.3
in welcher R2 eine niedere Alkylgruppe und R, X, Y, Z1 und Z2 die unter der Formel I angegebene Bedeutung haben, in einem organischen Lösungsmittel mit Wasserstoffperoxyd oder einer Persäure behandelt.

The present invention relates to a process for the preparation of new heterocyclic carboxylic acids.
Heterocyclic carboxylic acids of the formula I,
EMI1.1
in which
R is a lower alkyl group,
X oxygen. Sulfur, the imino group or the methylimino group,
Y hydrogen. Halogen up to atomic number 35 or the methyl group and
Z1 and Z2 denote hydrogen, halogen up to atomic number 35, a lower alkyl or alkoxy group, and their salts with inorganic or organic bases have not yet become known.
As has now been found, the new compounds have valuable pharmacological properties. They show diuretic and saluretic effects. These properties characterize these compounds as being suitable for the treatment of disorders which are caused by inadequate excretion of electrolytes, in particular sodium chloride. Such disorders are the cause of edema and hypertension. These compounds, e.g. B. 4-chloro5- (2-methylene-butyryl) -indole-2-carboxylic acid, 6-methoxy 5- (2-methylene-butyryl) -benzofuran-2-carboxylic acid and 6-methyl-5 - (2 -methylene-butyryl) -benzofuran-2-carboxylic acid can be used in dogs and rabbits at a dose of 10 mg / kg po to considerably increase the excretion of urine and the excretion of sodium ions and chlorine ions.
In the heterocyclic carboxylic acids of the formula I, Z1 is in the 4- or 6-position and Z2 is in the 6- or 7-position.
R, Z1 and Z2 are lower alkyl groups, for example methyl, ethyl, propyl, isopropyl, butyl or tert-butyl groups, and Zj and Z2 are lower alkoxy groups, for example methoxy, ethoxy, propoxy, isopropoxy -. Butoxy or the sec-butoxy group.
According to the process according to the invention, the compounds of the formula I are prepared by adding a compound of the formula II
EMI1.2
in which R, X, Y, Z1 and Z2 have the meaning given under formula I and R2 denotes a lower alkyl group, the alkyl sulfone group is split off by boiling in a hydroxyl-containing solvent in the presence of a weak base.
Sodium acetate or sodium hydrogen carbonate solutions can be used as weak bases, and water or a lower fatty acid can be used as the solvent.
The compounds of the formula II can be prepared in a simple manner by adding a compound of the formula III
EMI1.3
in which R2 is a lower alkyl group and R, X, Y, Z1 and Z2 have the meaning given under formula I, treated in an organic solvent with hydrogen peroxide or a peracid. Performic acid, peracetic acid, perbenzoic acid, etc. come into consideration as peracids and lower alkanols, ketones or lower fatty acids are advantageously used as organic solvents.
The compounds of the formula III can be prepared by, for example, a compound of the formula IV,
EMI1.4
in which R, X, Y, Zl and Z2 have the meaning given under formula I, and Am denotes the remainder of a secondary organic base, in the presence of a hydrohalic acid with excess lower alkyl sodium sulfide of the formula V, Na-S-R2 ( V) in which R2 has the meaning given under formula III, boils in a buffered aqueous solution of pH range 7-9 until the secondary amino group is replaced by the sulfide residue.
The compounds of the formula IV can in turn be prepared as follows:
One assumes a carboxylic acid of the formula V,
EMI1.5
in which X, Y, Zl and Z2 have the meaning given under formula I. These compounds can then be used according to Friedel-Crafts z. B. with the help of aluminum chloride in nitrobenzene with a carboxylic acid chloride of the formula VI,
R-CH2-COCI (VI) in which R has the meaning given under formula I, add to the corresponding 5-alkanoyl derivatives. Such 5-alkanoyl derivatives are e.g.
B. the 5-acetyl, 5-propionyl, 5-butyryl, 5-valeryl or 5-isovaleryl derivatives of benzofuran-2-carboxylic acid, benzo [bjthiophene-2-carboxylic acid, indole-2-carboxylic acid or the 1-alkyl-indole-2-carboxylic acids, which are optionally substituted by the radicals Y, Z1 and / or Z2. The 5-alkanoyl derivatives mentioned are then converted into the corresponding Mannich derivatives of the formula IV with the aid of formaldehyde or paraformaldehyde and a secondary organic base.
The new active ingredients or the pharmaceutically acceptable salts thereof are preferably administered orally. Inorganic or organic bases, such as, for example, alkali or alkaline earth metal hydroxides, carbonates or bicarbonates, triethanolamine or choline, can be used for salt formation. The daily doses range between 50 and 1000 mg for adult patients. Suitable dosage unit forms, such as coated tablets, tablets, preferably contain 25-500 mg of an active ingredient according to the invention, namely 2040% of a compound of the formula I.

Then let it cool down and acidify the solution with conc. Hydrochloric acid to pH 2-3. The mixture is stirred for a further 30 minutes, then the precipitated crystals are suction filtered, dried in vacuo and recrystallized from benzene.
