Description
Verfahren zur Herstellung von neuen Thiazocinderivaten
Die Erfindung betrifft ein Verfahren zur Herstellung von neuen TIiinzocinderivaten mit wertvollen pharmakologischen Eigenschaften.
Thiazocinderivate der Formel I,
EMI1.1
in weicher A eine unverzweigte oder verzweigte Alkylen gruppe von 2-5 Kohlenstoffatomen, R1 eine niedere Alkylgruppe, Wasserstoff oder eine niedere Alkylgruppe oder NR1(R2) gegebenenfalls mit der Iminogruppe, einer nie deren Alkylimino-, Hydroxyalkylimino-oder
Alkanoyloxyalkyliminogruppe als Ringglied einen gesättigten heterocyclischen Rest von 5-7
Ringgliedern bedeutet, sind bisher nicht bekanntgeworden.
Wie nun gefunden wurde, besitzen solche Verbindung gen und ihre Additionssalze mit anorganischen oder organischen Säuren bei peroraler, rektaler und parenteraler Verabreichung wertvolle zentrale und periphere pharmakologische Eigenschaften. Diese pharmakologischen Eigenschaften charakterisieren die neuen Verbindungen als geeignet zur Behandlung von Neurosen und Geisteskrankheiten. Sie können gewünschtenfalls auch mit anderen Pharamaka kombiniert werden.
In den Verbindungen der Formel I kann A z. B. die Äthylen-, Propylen¯, Trimethylen-, 1-Methyl-trimeth- ylen-, 2-Methyl-trimethylen-, l-Athyl-trimethylen- 2-Äthyl-trimethylen-, Tetramethylen-, 2-Methyl-tetramethylen- und 3-Methyl-tetramethylengruppe sein. Ferner sind R1 und R2 als niedere Alkylgruppen beispielsweise die Methyl-, Athyl-, Propyl-, Isopropyl-, Butyl-, Isobutyl-, sek.Butyl- und die tert.Butyigruppe und NR (R2) als heterocyclischer Rest z.
B. der l-Pyrroli- dinyl-, Piperidinio-, Hexahydro-1H-azepin-1-yl-, 1 Piperazinyl-, 4-Methyl-1-piperazinyl-, 4-(2-Hydroxy äthyl)-1-piperazinyl-, 4-(2-Acetoxy-äthyl)-1-piperazinyl-, Hexhydro-1H-1,4-diazepin-1-yl-, 4-Mcthyl-hexahydro1H-1,4-diazepin-1-yl- oder der 4-(2-Hydroxy-äthyl)hexahydro-1H-1,4-diazepin-1-yl-rest.
Erfindungsgemäss stellt man die Verbindungen, der Formel I her, indem man eine Verbindung der Formel II,
EMI1.2
mit einem reaktionsfähigen Ester einer Verbindung der Formel III,
EMI1.3
in welcher A, Rl, R2 und NR (R2) die unter Formel l angegebene Bedeutung haben, in Gegenwart eines basischen Kondeensationsmittels umsetzt, und gewünschtenalls die erhltene Verbindung mit einer anorganischen oder organischen Säure in ein Salz überführt.
Als Kondensationsmittel eignen sich insbesondere Natriumamid, Kaliumamid, Lithiumamid, Natrium, Kalium, Lithium, Butyllithium, Phenyllithium, Natriumtert.butylat, Natriumhydrid oder Lithiumhydrid. Die Umsetzung, bei der eine Reaktionstemperatur von ca.
50-250 eingehalten wird, kann in An- oder Abwesenheit eines inerten Lösungsmittels vorgenommen werden.
Geeignete organische Lösungsmittel sind beispielsweise Kohlenwasserstoffe, wie Benzol, Toluol, Xylol, Cumol, Tetralin, oder aliphatische Carbonsäureamide, wie Di methyhformamid.
Der Ausgangsstoff der Formel II kann z. B. hergestellt werden, indem man von dem in Ider Literatur be schriebenen Dibenzo[b,Üthiepin-1 0(11 lH)-onWoxim (vgl.
Dissertation L. Mirwald, Universität des Saarlandes [1961]) ausgeht und dieses mit Polyphosphorsäure zu dem 5H-Dibenzol[b,g][1,4]thiazocin-6(7H)-on umlagert, dessen Carbonylgruppe man mit Lithiumaluminiumhydrid reduziert.
Als reaktionsfähige Ester einer Verbindung der Formel III kommen die Halogenide, wie die Bromide, Jodide und insbesondere die Chloride, in Betracht. Ferner können Sulfonsäureester, wie z. B. Methansulfonsäureester oder p-Toluolsulfonsäureester, eingesetzt werden.
Die nach dem erfindungsgemässen Verfahren erhaltenen Verbindungen der Formel I werden anschliessend gewünschtenfalls in üblicher Weise in ihre Additionssalze mit anorganischen und organischen Säuren übergeführt.
Beispielsweise versetzt man eine Lösung einer Verbindung der Formel I in einem organischen Lösungsmittel mit der als Salzkomponente gewünschten Säure oder mit einer Lösung derselben. Vorzugsweise wählt man für die Umsetzung organische Lösungsmittel, in denen das entstehende Salz schwer löslich ist, damit es durch Filtration abgetrennt werden kann. Solche Lösungsmittel sind z. B. Methanol, Methanol/Äther oder AthanoVAther.
Zur Verwendung als Arzneistoffe können anstelle freier Basen nicht-toxische Säureadditionssalze eingesetzt werden, d. h. Salze mit solchen Säuren, deren Anionen bei den in Frage kommenden Dosierungen pharmazeutisch annehmbar sind. Ferner ist es von Vorteil, wenn die als Arzneistoffe zu verwendenden Salze gut kristallisierbar und nicht oder wenig hygroskopisch sind. Zur Salzbildung mit Verbindungen der Formel I können z.
B. die Chlorwasserstoffsäure, Bromwasserstoffsäure, Schwefelsäure, Phosphorsäure, Methansulfonsäure, Athan- sulfonsäure, ss-Hydroxyäthansulfonsäure, Essigsäure, Apfelsäure, Weinsäure, Citronensäure, Milchsäure, Oxalsäure, Bernsteinsäure, Fumarsäure, Maleinsäure, Benzoesäure, Salicylsäure, Phenylessigsäure, Mandelsäure und Embonsäure verwendet werden.
Die neuen Wirkstoffe werden, wie weiter vorne erwähnt, peroral, rektal und parenteral verabreicht. Die täglichen Dosen der freien Basen oder von nicht-toxischen Salzen derselben bewegen sich zwischen 10 und 800 mg für erwachsene Patienten. Geeignete Dosenein heltsformen, wie Dragees, Tabletten, Suppositorien oder Ampullen, enthalten vorzugsweise 5-50 mg eines erfindungsgemässen Wirkstoffs oder eines nicht-toxischen Salzes desselben. Ferner kommt auch die Anwendung entsprechender Mengen von nicht-einzeldosierben Applikationsformen, wie Sirups, Sprays, Aerosole, Salben oder Puder, in Betracht.
Doseneiinheitsformen für die perorale Anwendung enthalten als Wirkstoff vorzugsweise zwischen 1-90 % einer Verbindung der Formel I oder eines nicht-toxischen Salzes einer solchen.
Zu ihrer Herstellung kombiniert man den Wirkstoff z. B. mit festen, pulverförmigen Trägerstoffen, wie Lactose, Saccharose, Sorbit, Mannit; Stärken, wie Kartoffelstärke, Maisstärke oder Amylopektin, ferner Lariinaria- pulver oder Citruspulpenpulver; Cellulosederivaten oder Gelatine, gegebenenfalls unter Zusatz von Gleitmitteln, wie Magnesium- oder Calciumstearat oder Polyäthylenglykolen (Carbowaxen) von geeigneten Molekulargewichten zu Tabletten oder zu Dragee-Kernen. Letztere überzieht man beispielsweise mit konzentrierten Zukkerlösungen, welche z.
B. noch arabischen Gummi Talk und/oder Titandioxyd enthalten können, oder mit einem in leichtilüchtigen organischen Lösungsmitteln oder Lö sungsniittelgeniischen gelösten Lack. Diesen Überzügen können Farbstoffe zugefügt werden. z. B. zur Kennzeichnung verschiedener Wirkstoffdosen.
Als Doseneinheitsformen für die rektale Anwendung kommen z. B. Suppositorien, welche aus einer Kombination eines Wirkstoffes oder eines geeigneten Salzes desselben mit einer Neutralfettgrundlage bestehen, oder auch Gelatine-Rektalkapseln, welche eine Kombination des Wirkstoffes oder eines geeigneten Salzes desselben mit Polyäthylenglykolen (Carbowaxen) von geeignetem Molekulargewicht enthalten, in Betracht.
Ampullen zur parenteralen, insbesondere intramus kulären Verabreichung enthalten vorzugsweise ein wasserlösliches Salz eines Wirkstoffes in einer Konzentration von vorzugsweise 0,5-5 %, gegebenenfalls zusammen mit geeigneten Stabilisierungsmitteln und Puffersubstanzen, in wässeriger Lösung.

The suspension is stirred well, the precipitate is filtered off with suction and washed neutral with water.
The crude product is recrystallized from dioxane, after which the 5H-dibenzo [b, g] [1,4] thiazocin-6 (7H) -one obtained melts at 253-256. c) 35.0 g of the compound obtained according to Example 1b) are dissolved in 1.600 liters of warm abs. Tetrahydrofuran, this solution is added dropwise within one hour to a suspension of 14.5 g of lithium aluminum hydride in 150 ml of abs. Tetrahydrofuran and the reaction mixture refluxed for 3 hours. It is then allowed to cool to 200, 25 ml of water are slowly added dropwise, the precipitate formed is filtered off with suction and washed with tetrahydrofuran. The tetrahydrofuran is then distilled off and the residue is distilled in a high vacuum. The pure 6, 7-dihydro-5H-dibenzo [b, g] - [1,4] thiazocine boils at 136-139 / 0.005 torr.
Example 2
The following compounds are obtained analogously to Example la): a) 5- (3-dimethylaminopropyl) -6,7-dihydro-5H-dibenzo [b, g] [1,4] thiazocine with 3-dimethylaminopropyl chloride, bp. 153 / 0.002 Torr, and b) with 1- (2-chloro-ethyl) -pyrrolidine 5- (2- (1-pyrrolidinyl) -ethyl] -6,7-dihydro-5H-dibenzo [b, g] [ 1.4] thiazocin, b.p. 179 / 0.01 torr.
