Die Reaktionstemperaturen können - je nach Reaktivität der Edukte - in einem weiten Bereich variieren. Im allgemeinen wird die Umsetzung bei Temperaturen zwischen 20°C und 150°C, vorzugsweise zwischen 20°C und 100°C, insbesondere bei der Siedetemperatur des verwendeten Lösungsmittels durchgeführt.Depending on the reactivity of the starting materials, the reaction temperatures can vary within a wide range. In general, the reaction is carried out at temperatures between 20 ° C. and 150 ° C., preferably between 20 ° C. and 100 ° C., in particular at the boiling point of the solvent used.
Die Durchführung des erfindungsgemäßen Verfahrens gemäß 1. erfolgt in Gegenwart eines basischen Kondensationsmittels, beispielsweise in Gegenwart eines Alkalialkoholates, wie Natriummethylat oder Natriumethylat.The process according to the invention according to 1 is carried out in the presence of a basic condensing agent, for example in the presence of an alkali alcoholate, such as sodium methylate or sodium ethylate.

Bei der Durchführung des erfindungsgemäßen Verfahrens gemäß Varianten a bis f werden die an der Reaktion beteiligten Stoffe in der Regel jeweils in molaren Mengen eingesetzt, wobei jedoch - je nach Reaktionsbedingung - gewünschtenfalls auch ein Öberschuß (beispielsweise an Ammoniak bei den Varianten b und d) eingesetzt werden kann.When carrying out the process according to the invention according to variants a to f, the substances involved in the reaction are generally used in molar amounts, but - depending on the reaction condition - an excess (if desired, for example in ammonia in variants b and d) is also used can be.

If Z represents a hydroxyl group, for example, the reaction should preferably be carried out in the presence of a water-releasing or water-binding condensing agent (such as, for example, dicyclohexylcarbodiimide). If Z represents a halogen atom (eg a chlorine atom), then the reac tion, if desired, in the presence of a base (for example a tertiary organic amine such as triethylamine or an inorganic carbonate such as sodium carbonate).
Bei der Durchführung des Verfahrens gemäß Variante h kommen ähnliche Reaktionsbedingungen wie bei den Varianten a bis f zur Anwendung. Die Umsetzung erfolgt in einer Weise, wie sie für die Herstellung von sekundären bzw. tertiären Aminen bekannt ist. Je nach Art der Fluchtgruppe Y, die vorzugsweise ein Halogenatom, insbesondere ein Chlor- oder Bromatom ist, kann die Reaktion gewünschtenfalls in Gegenwart einer Base (z.B. eines anorganischen Carbonates, wie Kaliumcarbonat) oder unter Einsetzung eines Öberschusses von Amin XII durchgeführt werden.When carrying out the process according to variant h, similar reaction conditions are used as for variants a to f. The reaction takes place in a manner known for the production of secondary or tertiary amines. Depending on the nature of the leaving group Y, which is preferably a halogen atom, in particular a chlorine or bromine atom, the reaction can, if desired, be carried out in the presence of a base (e.g. an inorganic carbonate such as potassium carbonate) or by using an excess of amine XII.
Die enantiomer reinen Verbindungen und ihre Salze, die ebenfalls Gegenstand der Erfindung sind, erhält man beispielsweise, indem man die nach dem oben beschriebenen Verfahren erhaltenen Racemate mit einer enantiomer reinen optisch aktiven Säure umsetzt, die erhaltenen diastereomeren Salze trennt, aus den gewünschten diastereomeren Salze die Enantiomeren durch Zugabe von Base freisetzt und sie gewünschtenfalls anschließend in ihre Salze überführt.The enantiomerically pure compounds and their salts, which are also the subject of the invention, are obtained, for example, by reacting the racemates obtained by the process described above with an enantiomerically pure optically active acid, separating the diastereomeric salts obtained, from the desired diastereomeric salts Enantiomers are released by adding base and, if desired, subsequently converted into their salts.
Als optisch aktive Säuren seien beispielsweise die Di-0, 0'-p-toluoylweinsäure oder insbesondere die Di-0,0'-benzoylweinsäure genannt. Als Trennverfahren eignet sich vorzugsweise die Umkristallisation.Examples of optically active acids which may be mentioned are di-0, 0'-p-toluoyl tartaric acid or in particular di-0.0'-benzoyl tartaric acid. Recrystallization is preferably suitable as the separation process.
Die mit Hilfe dieser Methoden getrennten, konfigurativ einheitlichen diastereomeren Salze werden durch Zugabe vorzugsweise anorganischer Basen, wie z.B. Ammoniak, oder mit Hilfe von basischen Ionenaustauschern in die optisch aktiven, enantiomer reinen erfindungsgemäßen Verbindungen überführt.The configuratively uniform diastereomeric salts separated by means of these methods are obtained by adding preferably inorganic bases, such as e.g. Ammonia, or with the aid of basic ion exchangers in the optically active, enantiomerically pure compounds of the invention.
Dieses Verfahren zur Herstellung enantiomer reiner Verbindungen wird vorzugsweise für die Herstellung der enantiomer reinen Dihydropyridine der Ausgestaltung a eingesetzt.This process for the production of enantiomerically pure compounds is preferably used for the production of the enantiomerically pure dihydropyridines of embodiment a.
Alternativ erhält man die enantiomer reinen erfindungsgemäßen Verbindungen, indem man von enantiomer reinen Zwischenprodukten ausgeht. Hier sind insbesondere die enantiomer reinen 1,4-Dihydropyridine der Formel IX zu nennen, aus denen man durch Umsetzung mit den Aminderivaten X - wie bei Verfahrensvariante g beschrieben - die gewünschten enantiomer reinen erfindungsgemäßen Endprodukte erhält. Dieser Weg wird vorzugsweise zur Herstellung der enantiomer reinen Dihydropyridine der Ausgestaltung b eingeschlagen.Alternatively, the enantiomerically pure compounds according to the invention are obtained by starting from enantiomerically pure intermediates. The enantiomerically pure 1,4-dihydropyridines of the formula IX are particularly suitable here name, from which the desired enantiomerically pure end products according to the invention are obtained by reaction with the amine derivatives X - as described in process variant g. This route is preferably followed for the production of the enantiomerically pure dihydropyridines of embodiment b.
Die Isolierung und Reinigung der nach 1. oder 2. erhaltenen erfindungsgemäßen Substanzen erfolgt in an sich bekannter Weise z. B. derart, daß man das Lösungsmittel im Vakuum abdestilliert und den erhaltenen Rückstand aus einem geeigneten Lösungsmittel umkristallisiert oder einer der üblichen Reinigungsmethoden, wie beispielsweise der Säulenchromatographie an geeignetem Trägermaterial, unterwirft.The isolation and purification of the substances according to the invention obtained after 1 or 2 is carried out in a manner known per se, for. B. in such a way that the solvent is distilled off in vacuo and the residue obtained is recrystallized from a suitable solvent or subjected to one of the customary purification methods, such as, for example, column chromatography on a suitable carrier material.
Säureadditionssalze erhält man durch Auflösen der freien Base in einem geeigneten Lösungsmittel, z.B. in einem chlorierten Kohlenwasserstoff, wie Methylenchlorid oder Chloroform, oder einem niedermolekularen aliphatischen Alkohol (Ethanol, Isopropanol), das die gewünschte Säure enthalt, oder dem die gewünschte Säure anschließend zugegeben wird.Acid addition salts are obtained by dissolving the free base in a suitable solvent, e.g. in a chlorinated hydrocarbon, such as methylene chloride or chloroform, or a low molecular weight aliphatic alcohol (ethanol, isopropanol) which contains the desired acid or to which the desired acid is subsequently added.
Die Salze werden durch Filtrieren, Umfallen, Ausfällen mit einem Nichtlδsungsmittel für das Anlagerungssalz oder durch Verdampfen des Lösungsmittels gewonnen.The salts are obtained by filtering, reprecipitating, precipitating with a non-solvent for the addition salt or by evaporating the solvent.
Erhaltene Salze können durch Alkalisierung, z.B. mit wäßriger Ammoniaklösung, in die freien Basen umgewandelt werden, welche wiederum in Säureadditionssalze übergeführt werden können. Auf diese Weise lassen sich pharmakologisch nicht verträgliche Säureadditionssalze in pharmakologisch verträgliche Säureadditionssalze umwandeln.Salts obtained can be obtained by alkalization, e.g. with aqueous ammonia solution, are converted into the free bases, which in turn can be converted into acid addition salts. In this way, pharmacologically unacceptable acid addition salts can be converted into pharmacologically unacceptable acid addition salts.

Die antihypertensive Wirksamkeit der erfindungsgemäßen Verbindungen kann am Modell der spontan hypertonen Ratte nachgewiesen werden.The antihypertensive activity of the compounds according to the invention can be demonstrated on the model of the spontaneously hypertensive rat.
Zur Bestimmung der antihypertensiven Wirkung werden die unten aufgeführten Verbindungen in den angegebenen Dosen an vier aufeinander folgenden Tagen an je 6 männlichen Ratten (Stamm SHR/N/Ibm/8m, 250-350 g) mit genetisch bedingtem Hochdruck (systolischer Blutdruck > 180 mmHg) täglich einmal mittels Schlundsonde verabfolgt. Die Messung des Blutdrucks erfolgt jeweils 6 und gegebenenfalls 2 oder 24 Stunden nach Substanzgabe.To determine the antihypertensive effect, the compounds listed below are administered in the specified doses on four consecutive days on 6 male rats (strain SHR / N / Ibm / 8m, 250-350 g) with genetically determined high pressure (systolic blood pressure> 180 mmHg) administered once a day by gavage. Blood pressure is measured 6 and, if necessary, 2 or 24 hours after substance administration.
Die Blutdruckmessung wird in einer Wärmekammer bei 36ºC vorgenommen, um eine bessere Durchblutung der Schwanzarterie zu erreichen. Hierzu werden die Tiere in perforierte Lochblechkäfige verbracht und 20 - 40 Min. nach Beginn der Aufwärmung gemessen. Zur Messung des systolischen arteriellen Drucks wird eine ringförmige Manschette mit aufblasbarer Gummimembran zur Unterbindung der Durchblutung und ein ringförmiger Piezokristallaufnehmer zur Erfassung der Pulswellen auf den Schwanz aufgeschoben. Nach erfolgter Unterbindung des Blutstroms in der Schwanzarterie wird der Manschettendruck kontinuierlich reduziert. Die Wiederkehr der Pulswellen bei Druckablassen wird automatisch als systolischer Blutdruck erkannt und ausgedruckt (Bühler, R. et al.: Microprocessor-based automation of blood pressure measurement in the conscious rat. Proceedings of the 4th international Symposium on rats with spontaneous hypertension and related studies, Rascher, R. et al. (Eds.), Schattauer Verlag, Stuttgart, New York, 1982, S. 410-413). Pulssignale und Druckverlauf werden zur Auswertung graphisch aufgezeichnet.Blood pressure measurement is done in a warming chamber at 36 ° C to achieve better blood flow to the tail artery. For this purpose, the animals are placed in perforated perforated metal cages and measured 20-40 minutes after warming up. To measure the systolic arterial pressure, an annular cuff with an inflatable rubber membrane to prevent blood flow and an annular piezo crystal sensor to record the pulse waves are pushed onto the tail. After the blood flow in the tail artery has been stopped, the cuff pressure is continuously reduced. The return of the pulse waves during pressure relief is automatically recognized and printed out as systolic blood pressure (Bühler, R. et al .: Microprocessor-based automation of blood pressure measurement in the conscious rat. Proceedings of the 4th international Symposium on rats with spontaneous hypertension and related studies , Rascher, R. et al. (Eds.), Schattauer Verlag, Stuttgart, New York, 1982, pp. 410-413). Pulse signals and pressure curve are recorded graphically for evaluation.
