Der Erfindung lag die Aufgabe zugrunde, neue Verbindungen mit wert- vollen Eigenschaften aufzufinden, insbesondere solche, die zur Herstel¬ lung von Arzneimitteln verwendet werden können.The object of the invention was to find new compounds with valuable properties, in particular those which can be used for the production of medicaments.
Es wurde gefunden, daß die Verbindungen der Formel I und ihre physio¬ logisch unbedenklichen Salze bei guter Verträglichkeit wertvolle pharma- kologische Eigenschaften besitzen.It has been found that the compounds of the formula I and their physiologically acceptable salts, with good tolerability, have valuable pharmacological properties.
Bei den neuen Verbindungen handelt es sich um Inhibitoren des zellulären Na+/H+-Antiporters, d.h. um Wirkstoffe, die den NaVH+-Austauschmecha- nismus der Zellen hemmen (Düsing et al., Med. Klin. 8_Z, 378-384 (1992)) und die somit gute Antiarrhythmika darstellen, die sich insbesondere zur Behandlung von Arrhythmien eignen, die als Folge von Sauerstoffmangel auftreten. Der bekannteste Wirkstoff der Gruppe der Acylguanidine ist Amilorid. Diese Substanz zeigt jedoch in erster Linie eine blutdrucksenkende und saluretische Wirkung, was insbesondere bei der Behandlung von Herz- Rhythmus-Störungen unerwünscht ist, während die antiarrhythmischen Eigenschaften nur sehr schwach ausgeprägt sind.The new compounds are inhibitors of the cellular Na + / H + antiporter, ie active substances that inhibit the NaVH + exchange mechanism of the cells (Düsing et al., Med. Klin. 8_Z, 378-384 ( 1992)) and thus represent good antiarrhythmics, which are particularly suitable for the treatment of arrhythmias that occur as a result of lack of oxygen. The best-known active ingredient in the group of acylguanidines is amiloride. However, this substance primarily shows an antihypertensive and saluretic effect, which is particularly undesirable in the treatment of cardiac arrhythmia, while the antiarrhythmic properties are only very weak.
Benzoylguanidine sind z.B. in DE 44 04 183 beschrieben. Die im Stand der Technik beschriebenen Verbindungen sind jedoch strukturell deutlich von den hier beanspruchten verschieden.Benzoylguanidines are e.g. described in DE 44 04 183. However, the compounds described in the prior art are structurally distinctly different from those claimed here.
Gegenstand der Erfindung sind Verbindungen der Formel I sowie ihre physiologisch unbedenklichen Salze.The invention relates to compounds of the formula I and their physiologically acceptable salts.
Die erfindungsgemäßen Substanzen der vorliegenden Anmeldung zeigen eine gute kardioprotektive Wirkung und eignen sich daher besonders zur Infarktbehandlung, Infarktprophylaxe und zur Behandlung von Angina pectoris. Ferner wirken die Substanzen allen pathologischen hypoxischen und ischämischen Schädigungen entgegen, so daß die dadurch primär oder sekundär verursachten Krankheiten behandelt werden können. Die Wirkstoffe sind ebenfalls für präventive Anwendungen gut geeignet.The substances according to the invention of the present application show a good cardioprotective effect and are therefore particularly suitable for the treatment of infarct, prophylaxis of the infarct and for the treatment of angina pectoris. Furthermore, the substances counteract all pathological hypoxic and ischemic damage, so that the diseases caused primarily or secondarily can be treated. The active ingredients are also well suited for preventive applications.
Aufgrund der protektiven Wirkungen dieser Substanzen bei pathologi¬ schen, hypoxischen oder ischämischen Situationen resultieren daraus weitere Anwendungsmöglichkeiten bei chirurgischen Eingriffen zum Schutz zeitweilig minderversorgter Organe, bei Organtransplantationen zum Schutz der entnommenen Organe, bei angioplastischen Gefäß- oder Herzeingriffen, bei Ischämien des Nervensystems, bei der Therapie von Schockzuständen und zur präventiven Behandlung der essentiellen Hypertonie.Because of the protective effects of these substances in pathological, hypoxic or ischemic situations, this results in further possible uses in surgical interventions to protect temporarily under-supplied organs, in organ transplants to protect the removed organs, in angioplasty vascular or cardiac interventions, in ischemia of the nervous system, in the Therapy of shock conditions and for the preventive treatment of essential hypertension.
Ferner können die Verbindungen auch als Therapeutika bei durch Zell- proliferation bedingten Erkrankungen wie Arteriosklerose, diabetische Spätkomplikationen, Tumorerkrankungen, fibrotischen Erkrankungen, insbesondere von Lunge, Leber und Nieren sowie Organhypertrophien und -hyperplasien, eingesetzt werden. Darüber hinaus eignen sich die Substanzen zur diagnostischen Anwendung zur Erkennung von Krank¬ heiten, die von einer gesteigerten Aktivität des Na+/H+-Antiporters z.B. in Erythrozyten, Thrombozyten oder Leukozyten begleitet werden.Furthermore, the compounds can also be used as therapeutic agents in diseases caused by cell proliferation, such as arteriosclerosis, diabetic late complications, tumor diseases, fibrotic diseases, in particular of the lungs, liver and kidneys, and organ hypertrophies and hyperplasias. In addition, the Substances for diagnostic use for the detection of diseases which are accompanied by increased activity of the Na + / H + antiporter, for example in erythrocytes, thrombocytes or leukocytes.
Die Wirkungen der Verbindungen können mit Hilfe an sich bekannter Methoden ermittelt werden, wie sie z.B. von N. Escobales and J. Figueroa in J. Membrane Biol. 120, 41-49 (1991) oder von L Counillon, W. Scholz, HJ. Lang und J. Pouyssegur in Mol. Pharmacol. 44, 1041-1045 (1993) angegeben werden.The effects of the compounds can be determined with the aid of methods known per se, such as e.g. by N. Escobales and J. Figueroa in J. Membrane Biol. 120, 41-49 (1991) or by L Counillon, W. Scholz, HJ. Lang and J. Pouyssegur in Mol. Pharmacol. 44, 1041-1045 (1993).
Als Versuchstiere eignen sich z.B. Mäuse, Ratten, Meerschweinchen, Hunde, Katzen, Affen oder Schweine.Suitable experimental animals are e.g. Mice, rats, guinea pigs, dogs, cats, monkeys or pigs.
Die Verbindungen können daher als Arzneimittelwirkstoffe in der Human- und Veterinärmedizin verwendet werden. Ferner können sie als Zwischen¬ produkte zur Herstellung weiterer Arzneimittelwirkstoffe Verwendung finden.The compounds can therefore be used as active pharmaceutical ingredients in human and veterinary medicine. They can also be used as intermediate products for the production of further active pharmaceutical ingredients.

und/oder daß man eine erhaltene Base der Formel I durch Behandeln mit einer Säure in eines ihrer Salze umwandelt.and / or that a base of formula I obtained is converted into one of its salts by treatment with an acid.
Die Verbindungen der Formel I werden im übrigen nach an sich bekannten Methoden hergestellt, wie sie in der Literatur (z.B. in den Standardwerken wie Houben-Weyl, Methoden der organischen Chemie, Georg-Thieme- Verlag, Stuttgart; Organic Reactions, John Wiley & Sons, Inc., New York; sowie in der oben angegebenen Patentanmeldung) beschrieben sind, und zwar unter Reaktionsbedingungen, die für die genannten Umsetzungen bekannt und geeignet sind. Dabei kann man auch von an sich bekannten, hier nicht näher erwähnten Varianten Gebrauch machen.The compounds of the formula I are otherwise prepared by methods known per se, as described in the literature (for example in the standard works such as Houben-Weyl, Methods of Organic Chemistry, Georg-Thieme-Verlag, Stuttgart; Organic Reactions, John Wiley & Sons , Inc., New York; and in the above-mentioned patent application), under reaction conditions which are known and suitable for the reactions mentioned. Use can also be made of variants which are known per se and are not mentioned here in detail.
Die Ausgangsstoffe können gewünschtenfalls auch in situ gebildet wer¬ den, derart, daß man sie aus dem Reaktionsgemisch nicht isoliert, son¬ dern sofort weiter zu den Verbindungen der Formel I umsetzt. Vorzugsweise werden Verbindungen der Formel I hergestellt, indem man ein aktiviertes Carbonsäurederivat der Formel II, wobei Q besonders be¬ vorzugt Cl oder -0-CH3 ist, mit Guanidin umsetzt. Besonders geeignet sind auch Reaktionsvarianten, bei denen die freie Carbonsäure II (Q = OH) in an sich bekannter Weise zu dem jeweiligen aktivierten Derivat um¬ gesetzt und dieses dann direkt, ohne Zwischenisolierung, mit Guanidin zur Reaktion gebracht wird. Methoden, bei denen eine Zwischenisolierung entbehrlich ist, sind beispielsweise eine Aktivierung mit Carbonyldiimida- zol, Dicyclohexylcarbodiimid oder die Mukayama-Variante (Angew. Chem. 91, 788-812 (1979)).If desired, the starting materials can also be formed in situ, in such a way that they are not isolated from the reaction mixture, but instead are immediately reacted further to give the compounds of the formula I. Compounds of the formula I are preferably prepared by reacting an activated carboxylic acid derivative of the formula II, where Q is particularly preferably Cl or -0-CH 3 , with guanidine. Also particularly suitable are reaction variants in which the free carboxylic acid II (Q = OH) is converted to the respective activated derivative in a manner known per se and this is then reacted directly with guanidine, without intermediate isolation. Methods in which intermediate isolation is unnecessary are, for example, activation with carbonyldiimidazole, dicyclohexylcarbodiimide or the Mukayama variant (Angew. Chem. 91, 788-812 (1979)).

Formel II mit Guanidin erfolgt in an sich bekannter Weise vorzugsweise in einem protischen oder aprotischen polaren oder unpolaren inerten organischen Lösungsmittel.Formula II with guanidine is carried out in a manner known per se, preferably in a protic or aprotic polar or non-polar inert organic solvent.
Eine bevorzugte Variante besteht allerdings auch darin, daß man dieA preferred variant is, however, that the
Reaktionspartner direkt, ohne Zusatz eines Lösungsmittels, miteinander zur Reaktion bringt.Reacting reactants directly with one another without the addition of a solvent.
Bei der Herstellung von II oder bei der Umsetzung von II mit Guanidin ist es ebenfalls zweckmäßig, in Gegenwart einer Base oder mit einem Über¬ schuß der basischen Komponente zu arbeiten. Als Basen eignen sich bevorzugt z.B. Alkalimetall- oder Erdalkalimetallhydroxide, -carbonate, -alkoholate oder organische Basen wie Triethylamin oder Pyridin, die auch im Überschuß angewendet werden und dann gleichzeitig als Lösungs- mittel dienen können. Als inerte Lösungsmittel eignen sich insbesondere Alkohole wie Methanol, Ethanol, Isopropanol, n-Butanol oder tert.-Butanol; Ether wie Diethylether, Diisopropylether, THF oder Dioxan; Glykolether wie Ethylenglykolmono- methyl- oder -monoethylether (Methylglykol oder Ethylglykol), Ethylen- glykoldimethylether (Diglyme); Ketone wie Aceton oder Butanon; Nitrile wie Acetonitril; Nitroverbindungen wie Nitromethan oder Nitrobenzol; Ester wie Ethylacetat; Amide wie Phosphorsäurehexamethyltriamid; Sulfoxide wie Dimethylsulfoxid (DMSO); chlorierte Kohlenwasserstoffe wie Dichlor¬ methan, Chloroform, Trichlorethylen, 1 ,2-Dichlorethan oder Kohlenstoff- tetrachlorid; Kohlenwasserstoffe wie Benzol, Toluol oder Xylol. Weiterhin eignen sich Gemische dieser Lösungsmittel untereinander.In the preparation of II or in the reaction of II with guanidine, it is also expedient to work in the presence of a base or with an excess of the basic component. Suitable bases are preferably, for example, alkali metal or alkaline earth metal hydroxides, carbonates, alcoholates or organic bases such as triethylamine or pyridine, which are also used in excess and can then simultaneously serve as solvents. Alcohols such as methanol, ethanol, isopropanol, n-butanol or tert-butanol are particularly suitable as inert solvents; Ethers such as diethyl ether, diisopropyl ether, THF or dioxane; Glycol ethers such as ethylene glycol monomethyl or monoethyl ether (methyl glycol or ethyl glycol), ethylene glycol dimethyl ether (diglyme); Ketones such as acetone or butanone; Nitriles such as acetonitrile; Nitro compounds such as nitromethane or nitrobenzene; Esters such as ethyl acetate; Amides such as phosphoric acid hexamethyl triamide; Sulfoxides such as dimethyl sulfoxide (DMSO); chlorinated hydrocarbons such as dichloromethane, chloroform, trichlorethylene, 1, 2-dichloroethane or carbon tetrachloride; Hydrocarbons such as benzene, toluene or xylene. Mixtures of these solvents with one another are also suitable.
Besonders geeignete Lösungsmittel sind Methanol, THF, Dimethoxyethan, Dioxan, Wasser oder daraus herstellbare Gemische. Als Reaktions- temperatur sind beispielsweise Temperaturen zwischen 20° und dem Siedepunkt des Lösungsmittels geeignet. Die Reaktionszeiten liegen zwischen 5 Min. und 12 Std.. Es ist zweckmäßig, bei der Reaktion einen Säurefänger einzusetzen. Hierzu eignen sich jeglische Arten von Basen, die die Reaktion selbst nicht stören. Besonders geeignet ist jedoch die Verwendung von anorganischen Basen wie Kaliumcarbonat oder von organischen Basen wie Triethylamin oder Pyridin oder aber ein Überschuß des Guanidins.Particularly suitable solvents are methanol, THF, dimethoxyethane, dioxane, water or mixtures which can be prepared therefrom. For example, temperatures between 20 ° and the boiling point of the solvent are suitable as the reaction temperature. The reaction times are between 5 minutes and 12 hours. It is advisable to use an acid scavenger in the reaction. Any type of base that does not interfere with the reaction itself is suitable for this. However, the use of inorganic bases such as potassium carbonate or of organic bases such as triethylamine or pyridine or an excess of guanidine is particularly suitable.
Weiterhin können die Verbindungen der Formel I erhalten werden, indem man sie aus ihren funktionellen Derivaten durch Solvolyse, insbesondereFurthermore, the compounds of the formula I can be obtained by removing them from their functional derivatives by solvolysis, in particular

Bevorzugte Ausgangsstoffe für die Solvolyse bzw. Hydrogenolyse sind solche, die sonst der Formel I entsprechen, aber anstelle einer oder meh- rerer freier Amino- und/oder Hydroxygruppen entsprechende geschütztePreferred starting materials for solvolysis or hydrogenolysis are those which otherwise correspond to the formula I, but instead of one or more free amino and / or hydroxyl groups, correspondingly protected groups

Es können auch mehrere - gleiche oder verschiedene - geschützte Amino- und/oder Hydroxygruppen im Molekül des Ausgangsstoffes vorhanden sein. Falls die vorhandenen Schutzgruppen voneinander verschieden sind, können sie in vielen Fällen selektiv abgespalten werden.Several - identical or different - protected amino and / or hydroxy groups can also be present in the molecule of the starting material. If the existing protective groups are different from one another, they can in many cases be split off selectively.
Der Ausdruck "Aminoschutzgruppe" ist allgemein bekannt und bezieht sich auf Gruppen, die geeignet sind, eine Aminogruppe vor chemischen Umset¬ zungen zu schützen (zu blockieren), die aber leicht entfernbar sind, nach¬ dem die gewünschte chemische Reaktion an einer anderen Stelle des Moleküls durchgeführt worden ist. Typisch für solche Gruppen sind insbe¬ sondere unsubstituierte oder substituierte Acyl-, Aryl- (z.B. 2,4-Dinitro- phenyl (DNP)), Aralkoxymethyl- (z.B. Benzyloxymethyl (BOM)) oder Aral- kylgruppen (z.B. Benzyl, 4-Nitrobenzyl, Triphenylmethyl). Da die Amino- schutzgruppen nach der gewünschten Reaktion (oder Reaktionsfolge) entfernt werden, ist ihre Art und Größe im übrigen nicht kritisch; bevorzugt werden jedoch solche mit 1-20, insbesondere 1-8 C-Atomen. Der Ausdruck "Acylgruppe" ist im Zusammenhang mit dem vorliegenden Verfahren im weitesten Sinne aufzufassen. Er umschließt von aliphati¬ schen, araliphatischen, aromatischen oder heterocyclischen Carbon- säuren oder Sulfonsäuren abgeleitete Acylgruppen sowie insbesondereThe term "amino protecting group" is generally known and refers to groups which are suitable for protecting (blocking) an amino group from chemical reactions, but which are easily removable after the desired chemical reaction has occurred at another point on the Molecule has been carried out. Typical of such groups are in particular unsubstituted or substituted acyl, aryl (for example 2,4-dinitrophenyl (DNP)), aralkoxymethyl (for example benzyloxymethyl (BOM)) or aralkyl groups (for example benzyl, 4-nitrobenzyl) , Triphenylmethyl). Since the amino protective groups are removed after the desired reaction (or reaction sequence), their type and size is otherwise not critical; however, preference is given to those having 1-20, in particular 1-8, carbon atoms. The term "acyl group" is to be understood in the broadest sense in connection with the present process. It encompasses acyl groups derived from aliphatic, araliphatic, aromatic or heterocyclic carboxylic acids or sulfonic acids, and in particular
Alkoxycarbonyl-, Aryloxycarbonyl- und vor allem Aralkoxycarbonyl- gruppen. Beispiele für derartige Acylgruppen sind Alkanoyl wie Acetyl, Propionyl, Butyryl; Aralkanoyl wie Phenylacetyl; Aroyl wie Benzoyl oder Toluoyl; Aryloxyalkanoyl wie Phenoxyacetyl; Alkoxycarbonyl wie Methoxy- carbonyl, Ethoxycarbonyl, 2,2,2-Trichlorethoxycarbonyl, Isopropoxy- carbonyl, tert. -Butoxycarbonyl (BOC), 2-Jodethoxycarbonyl; Aralkyloxy- carbonyl wie Benzyloxycarbonyl (CBZ), 4-Methoxybenzyloxycarbonyl, 9-Fluorenylmethoxycarbonyl (FMOC). Bevorzugte Aminoschutzgruppen sind BOC, DNP und BOM, ferner CBZ, Benzyl und Acetyl. Der Ausdruck "Hydroxyschutzgruppe" ist ebenfalls allgemein bekannt und bezieht sich auf Gruppen, die geeignet sind, eine Hydroxygruppe vor chemischen Umsetzungen zu schützen, die aber leicht entfernbar sind, nachdem die gewünschte chemische Reaktion an einer anderen Stelle des Moleküls durchgeführt worden ist. Typisch für solche Gruppen sind die oben genannten unsubstituierten oder substituierten Aryl-, Aralkyl- oder Acylgruppen, ferner auch Alkylgruppen. Die Natur und Größe der Hydroxy- schutzgruppen ist nicht kritisch, da sie nach der gewünschten chemischen Reaktion oder Reaktionsfolge wieder entfernt werden; bevorzugt sind Gruppen mit 1-20, insbesondere 1-10 C-Atomen. Beispiele für Hydroxy- schutzgruppen sind u.a. tert.-Butyl, Benzyl, p-Nitrobenzyl, p-Toluol- sulfonyl und Acetyl, wobei Benzyl und Acetyl besonders bevorzugt sind.Alkoxycarbonyl, aryloxycarbonyl and especially aralkoxycarbonyl groups. Examples of such acyl groups are alkanoyl such as acetyl, propionyl, butyryl; Aralkanoyl such as phenylacetyl; Aroyl such as benzoyl or toluoyl; Aryloxyalkanoyl such as phenoxyacetyl; Alkoxycarbonyl such as methoxycarbonyl, ethoxycarbonyl, 2,2,2-trichloroethoxycarbonyl, isopropoxycarbonyl, tert. -Butoxycarbonyl (BOC), 2-iodoethoxycarbonyl; Aralkyloxycarbonyl such as benzyloxycarbonyl (CBZ), 4-methoxybenzyloxycarbonyl, 9-fluorenylmethoxycarbonyl (FMOC). Preferred amino protecting groups are BOC, DNP and BOM, furthermore CBZ, benzyl and acetyl. The term "hydroxyl protecting group" is also generally known and refers to groups which are suitable for protecting a hydroxyl group against chemical reactions, but which are easily removable after the desired chemical reaction has been carried out elsewhere in the molecule. Typical of such groups are the unsubstituted or substituted aryl, aralkyl or acyl groups mentioned above, and also alkyl groups. The nature and size of the hydroxyl protective groups is not critical since they are removed again after the desired chemical reaction or reaction sequence; groups with 1-20, in particular 1-10, carbon atoms are preferred. Examples of hydroxyl protecting groups include tert-butyl, benzyl, p-nitrobenzyl, p-toluenesulfonyl and acetyl, with benzyl and acetyl being particularly preferred.
Die als Ausgangsstoffe zu verwendenden funktionellen Derivate der Verbindungen der Formel I können nach üblichen Methoden hergestellt werden, wie sie z.B. in den genannten Standardwerken und Patent¬ anmeldungen beschrieben sind, z.B. durch Umsetzung von Verbindungen, die den Formeln II und III entsprechen, wobei jedoch mindestens eine dieser Verbindungen eine Schutzgruppe anstelle eines H-Atoms enthält.The functional derivatives of the compounds of the formula I to be used as starting materials can be prepared by customary methods, such as those e.g. are described in the mentioned standard works and patent applications, e.g. by reacting compounds corresponding to formulas II and III, but at least one of these compounds contains a protective group instead of an H atom.
Das In-Freiheit-Setzen der Verbindungen der Formel I aus ihren funktio¬ nellen Derivaten gelingt - je nach der benutzten Schutzgruppe - z.B. mit starken Säuren, zweckmäßig mit Trifluoressigsäure oder Perchlorsäure, aber auch mit anderen starken anorganischen Säuren wie Salzsäure oder Schwefelsäure, starken organischen Carbonsäuren wie Trichloressigsäure oder Sulfonsäuren wie Benzol- oder p-Toluolsulfonsäure. Die Anwesenheit eines zusätzlichen inerten Lösungsmittels ist möglich, aber nicht immer erforderlich.The liberation of the compounds of formula I from their functional derivatives succeeds - depending on the protective group used - e.g. with strong acids, suitably with trifluoroacetic acid or perchloric acid, but also with other strong inorganic acids such as hydrochloric acid or sulfuric acid, strong organic carboxylic acids such as trichloroacetic acid or sulfonic acids such as benzene or p-toluenesulfonic acid. The presence of an additional inert solvent is possible, but not always necessary.
Als inerte Lösungsmittel eignen sich vorzugsweise organische, beispiels¬ weise Carbonsäuren wie Essigsäure, Ether wie Tetrahydrofuran (THF) oder Dioxan, Amide wie Dimethylformamid (DMF), halogenierte Kohlen¬ wasserstoffe wie Dichlormethan, ferner auch Alkohole wie Methanol, Ethanol oder Isopropanol sowie Wasser. Ferner kommen Gemische der vorgenannten Lösungsmittel in Frage. Trifluoressigsäure wird vorzugs¬ weise im Überschuß ohne Zusatz eines weiteren Lösungsmittels verwen¬ det, Perchlorsäure in Form eines Gemisches aus Essigsäure und 70%iger Perchlorsäure im Verhältnis 9:1. Die Reaktionstemperaturen für die Spal- tung liegen zweckmäßig zwischen etwa 0 und etwa 50°; vorzugsweise arbeitet man zwischen 15 und 30° (Raumtemperatur).Suitable inert solvents are preferably organic, for example carboxylic acids such as acetic acid, ethers such as tetrahydrofuran (THF) or dioxane, amides such as dimethylformamide (DMF), halogenated hydrocarbons such as dichloromethane, and also alcohols such as methanol, ethanol or isopropanol and water. There are also mixtures of aforementioned solvents in question. Trifluoroacetic acid is preferably used in excess without the addition of another solvent, perchloric acid in the form of a mixture of acetic acid and 70% perchloric acid in a ratio of 9: 1. The reaction temperatures for the cleavage are advantageously between about 0 and about 50 °; preferably one works between 15 and 30 ° (room temperature).

Dimethylamin, Diethylamin oder Piperidin in DMF bei 15-50°. Eine Abspal¬ tung der DNP-Gruppe gelingt z.B. auch mit einer etwa 3-10%igen Lösung von 2-Mercaptoethanol in DMF/Wasser bei 15-30°.Dimethylamine, diethylamine or piperidine in DMF at 15-50 °. The DNP group can be split off, e.g. also with an approximately 3-10% solution of 2-mercaptoethanol in DMF / water at 15-30 °.
Hydrogenolytisch entfernbare Schutzgruppen (z.B. BOM, CBZ oderHydrogenolytically removable protective groups (e.g. BOM, CBZ or
Benzyl) können z.B. durch Behandeln mit Wasserstoff in Gegenwart eines Katalysators (z.B. eines Edelmetallkatalysators wie Palladium, zweck¬ mäßig auf einem Träger wie Kohle) abgespalten werden. Als Lösungs¬ mittel eignen sich dabei die oben angegebenen, insbesondere z.B. Alkohole wie Methanol oder Ethanol oder Amide wie DMF. Die Hydro¬ genolyse wird in der Regel bei Temperaturen zwischen etwa 0 und 100° und Drucken zwischen etwa 1 und 200 bar, bevorzugt bei 20-30° und 1-10 bar durchgeführt. Eine Hydrogenolyse der CBZ-Gruppe gelingt z.B. gut an 5-10%igem Pd-C in Methanol bei 20-30°.Benzyl) can e.g. by treatment with hydrogen in the presence of a catalyst (e.g. a noble metal catalyst such as palladium, suitably on a support such as coal). Suitable solvents are those given above, in particular e.g. Alcohols like methanol or ethanol or amides like DMF. Hydrogenation is generally carried out at temperatures between about 0 and 100 ° and pressures between about 1 and 200 bar, preferably at 20-30 ° and 1-10 bar. Hydrogenolysis of the CBZ group succeeds e.g. good on 5-10% Pd-C in methanol at 20-30 °.
Eine Base der Formel I kann ferner mit einer Säure in das zugehörige Säureadditionssalz übergeführt werden. Für diese Umsetzung kommen Säuren in Frage, die physiologisch unbedenkliche Salze liefern. So können anorganische Säuren verwendet werden, z.B. Schwefelsäure. Salpetersäure, Halogenwasserstoffsäuren wie Chlorwasserstoffsäure oder Bromwasserstoffsaure, Phosphorsäuren wie Orthophosphorsäure, Sulfa- minsäure, ferner organische Säuren, insbesondere aliphatische, alicycli- sche, araliphatische, aromatische oder heterocyclische ein- oder mehr- basige Carbon-, Sulfon- oder Schwefelsäuren, z.B. Ameisensäure, Essig¬ säure, Propionsäure, Pivalinsäure, Diethylessigsäure, Malonsäure, Bern¬ steinsäure, Pimelinsäure, Fumarsaure, Maleinsäure, Milchsäure, Wein¬ säure, Äpfelsäure, Benzoesäure, Salicylsäure, 2- oder 3-Phenylpropion- säure, Citronensäure, Gluconsäure, Ascorbinsäure, Nicotinsäure, Isonico- tinsäure, Methan- oder Ethansulf onsäure, Ethandisulf onsäure, 2-Hydroxy- ethansulfonsäure, Benzolsulfonsäure, p-Toluolsulfonsäure, Naphthalin- mono- und -disulfonsäuren, Laurylschwefelsäure.A base of the formula I can also be converted into the associated acid addition salt using an acid. Acids which provide physiologically acceptable salts are suitable for this reaction. So inorganic acids can be used, for example sulfuric acid. Nitric acid, hydrohalic acids such as hydrochloric acid or hydrobromic acid, phosphoric acids such as orthophosphoric acid, sulfamic acid, furthermore organic acids, in particular aliphatic, alicyclic, araliphatic, aromatic or heterocyclic mono- or poly- basic carboxylic, sulfonic or sulfuric acids, e.g. formic acid, acetic acid, propionic acid, pivalic acid, diethyl acetic acid, malonic acid, succinic acid, pimelic acid, fumaric acid, maleic acid, lactic acid, tartaric acid, malic acid, benzoic acid, salicylic acid, 2- or 3 -Phenylpropionic acid, citric acid, gluconic acid, ascorbic acid, nicotinic acid, isonicotinic acid, methane or ethanesulfonic acid, ethane disulfonic acid, 2-hydroxyethanesulfonic acid, benzenesulfonic acid, p-toluenesulfonic acid, naphthalene mono- and disulfonic acids, laurylsulfonic acid.
Die Verbindungen der Formel I enthalten ein oder mehrere chirale Zentren und können daher in racemischer oder in optisch- aktiver Form vorliegen. Erhaltene Racemate können nach an sich bekannten Methoden mecha¬ nisch oder chemisch in die Enantiomeren getrennt werden. Vorzugsweise werden aus dem racemischen Gemisch durch Umsetzung mit einem optisch-aktiven Trennmittel Diastereomere gebildet. Als Trennmittel eig¬ nen sich z.B. optisch aktive Säuren, wie die D- und L-Formen von Wein¬ säure, Diacetylweinsäure, Dibenzoylweinsäure, Mandelsäure, Äpfelsäure, Milchsäure oder die verschiedenen optisch-aktiven Camphersulfonsäuren wie ß-Camphersulfonsäure. Vorteilhaft ist auch eine Enantiomerentren- nung mit Hilfe einer mit einem optisch aktiven Trennmittel (z.B. Dinitro- benzoylphenyl-glycin) gefüllten Säule.The compounds of the formula I contain one or more chiral centers and can therefore be present in racemic or in optically active form. Racemates obtained can be separated mechanically or chemically into the enantiomers by methods known per se. Diastereomers are preferably formed from the racemic mixture by reaction with an optically active release agent. Suitable release agents are e.g. optically active acids, such as the D and L forms of tartaric acid, diacetyl tartaric acid, dibenzoyl tartaric acid, mandelic acid, malic acid, lactic acid or the various optically active camphorsulfonic acids such as ß-camphorsulfonic acid. Enantiomer separation using a column filled with an optically active separating agent (e.g. dinitrobenzoylphenylglycine) is also advantageous.
Natürlich ist es auch möglich, optisch-aktive Verbindungen der Formel I nach den oben beschriebenen Methoden zu erhalten, indem man Ausgangsstoffe (z.B. solche der Formell II) verwendet, die bereits optisch¬ aktiv sind.Of course, it is also possible to obtain optically active compounds of the formula I by the methods described above by using starting materials (for example those of the formula II) which are already optically active.
