Description
1,1-Ethanoretinsäuren und ihre Cl-C4-Alkylester1,1-ethanoretinic acids and their C1-C4-alkyl esters
Die Erfindung betrifft 1,1-EthanoretinsSuren, also neue Spiroretinsäuren der Formel ihre physiologisch unbedenklichen Salze und deren Cl-C4-Alkylester, ein Verfahren zu ihrer Herstellung und ihre Verwendung bei der Bekämpfung von Krankheiten.The invention relates to 1,1-ethanoretinic acids, i.e. new spiroretinic acids of the formula their physiologically harmless salts and their Cl-C4-alkyl esters, a process for their preparation and their use in combating diseases.
Die verschiedensten Aspekte der Retinsäure und ihrer bis dahin bekannten Derivate sind beispielsweise beschrieben in 0. Isler, Carotenoids, Birkhäuser-Verlag, Basel und Stuttgart, 1971. Die Anwendung von Retinsäure (= Vitamin A-Säure) zur Bekämpfung von Akne ist beschrieben in US-PS 3 729 568.The most diverse aspects of retinoic acid and its previously known Derivatives are described, for example, in 0. Isler, Carotenoids, Birkhäuser-Verlag, Basel and Stuttgart, 1971. The use of retinoic acid (= vitamin A acid) for Combating acne is described in U.S. Patent No. 3,729,568.
Es sind auch schon Ethanoderivate der Retinsäure und ihre pharmakologischen Aktivitäten beschrieben, vgl. M.I. Dawson et al, J. Med. Chem. 24 (1981), 1214 bis 1223.There are also ethano derivatives of retinoic acid and their pharmacological ones Activities described, see M.I. Dawson et al (1981) J. Med. Chem. 24: 1214 bis 1223.
Die Retinsäure und ihre bisher bekannten Derivate sind zwar meist mehr oder weniger gut wirksam bei der topischen und systemischen Therapie von Neoplasien, Akne, Psoriasis und anderen dermatologischen Affektionen, sie zeigen aber auch alle mehr oder weniger starke toxische Nebenwirkungen.Retinoic acid and its previously known derivatives are mostly more or less effective in topical and systemic therapy of neoplasms, Acne, psoriasis, and other dermatological ailments, but they all show up too more or less severe toxic side effects.
Der Erfindung lag daher die Aufgabe zugrunde, Retinsäurederivate mit größerer therapeutischer Breite und gegebenenfalls anderem Wirkprofil zu entwickeln.The invention was therefore based on the object of using retinoic acid derivatives to develop a wider therapeutic range and possibly a different action profile.
Die Lösung dieser Aufgabe besteht in der 1,1-EthanoretinsSure (I) und deren Cl~C4-AlkYlestern, und zwar sowohl in Form des cis-trans-Isomerengemisches als auch der reinen cis- und trans-Isomeren, und in einem Verfahren zu deren Herstellung, dessen letzte Stufe im Anspruch 3 und das insgesamt im folgenden beschrieben ist.The solution to this problem is 1,1-ethanoretinic acid (I) and their Cl ~ C4-alkyl esters, both in the form of the cis-trans isomer mixture as well as the pure cis and trans isomers, and in a process for their preparation, the last stage of which is described in claim 3 and as a whole in the following.
Die Herstellung wird am Beispiel des Methylesters beschrieben. Die Darstellung des Ethyl- bis Butylesters erfolgt analog. Aus dem Ester kann durch Hydrolyse ohne weiteres die freie Säure hergestellt werden.The preparation is described using the example of the methyl ester. the The ethyl to butyl ester is prepared analogously. From the ester can through Hydrolysis readily produces the free acid.
2-Methylcyclohexanon wird mit einem Alkalidialkylamid zum Enolat (II) und dieses weiter mit Chlortrimethylsilan zum Silylenolether (III) umgesetzt. 2-Methylcyclohexanone is reacted with an alkali dialkylamide to form the enolate (II) and this is further reacted with chlorotrimethylsilane to form the silyl enol ether (III).
M = Alkalimetall = = Methyl Die Reaktionsbedingungen sind dem Fachmann geläufig: absolut wasserfreies Medium, inerte Atmosphäre, tiefe Temperatur, aprotische Lösungsmittel, vorzugsweise ein Ether wie Diethylether oder Tetrahydrofuran. Als Alkalimetall wird Natrium und vor allem Lithium vorgezogen. Die Aufarbeitung erfolgt nach üblichen Methoden, hauptsächlich destillativ unter vermindertem Druck. M = alkali metal = = methyl The reaction conditions are known to those skilled in the art Common: absolutely anhydrous medium, inert atmosphere, low temperature, aprotic Solvent, preferably an ether such as diethyl ether or tetrahydrofuran. as Alkali metal is preferred over sodium and especially lithium. The work-up takes place by customary methods, mainly by distillation under reduced pressure.
Der Silylenolether (III) wird mit Zinkdiethyl- und Methyleniodid zur Spiro-Verbindung (IV) umgesetzt. Die Reaktionsbedingungen und die Aufarbeitung sind prinzipiell die gleichen wie bei der ersten Umsetzung.The Silylenolether (III) is with zinc diethyl and methylene iodide for Spiro compound (IV) implemented. The reaction conditions and work-up are basically the same as with the first implementation.
Dann wird die Silyletherbindung mit wäßriger Säure gespalten und man erhält den Spiroalkohol V. The silyl ether bond is then cleaved with aqueous acid and the spiro alcohol V is obtained.
Der Alkohol V kann nach einer der üblichen Methoden, beispielsweise mit Chromat, zum entsprechenden Keton VI oxidiert werden. Dieses wird mit Li-Acetylenid in flüssigem Ammoniak zum 4-Ethinyl-5-methylspiro2.5]-octan-4-ol (VII) umgesetzt. The alcohol V can be oxidized to the corresponding ketone VI by one of the customary methods, for example with chromate. This is reacted with Li-acetylenide in liquid ammonia to form 4-ethynyl-5-methylspiro2.5] -octan-4-ol (VII).
VII wird nach üblichen Methoden, vorzugsweise mit Hilfe von Isocyanat, dehydratisiert zum Enin VIII.VII is by customary methods, preferably with the help of isocyanate, dehydrated to enyne VIII.
Das Enin VIII wird in wasserfreiem, etwa -30 bis -500C kaltem Ether oder Tetrahydrofuran mit einem metall-organischen Reagenz, z.B. Butyllithium, metalliert, anschließend bei etwa 30 bis 800C mit Acetylacetaldehyddimethylacetal umgesetzt, und das Reaktionsprodukt anschließend mit etwas Eiswasser zum acetylenischen Spiro-C15-hydroxyacetal IX hydrolysiert. The enyne VIII is metalated in anhydrous, about -30 to -500C cold ether or tetrahydrofuran with an organometallic reagent, e.g. butyllithium, then reacted at about 30 to 800C with acetylacetaldehyde dimethyl acetal, and the reaction product is then mixed with a little ice water to form the acetylenic spiro C15 hydroxyacetal IX hydrolyzed.
Die 3-fach-Bindung in IX wird selektiv zur Doppelbindung hydriert, beispielsweise mit Lithiumalanat in absolutem Tetrahydrofuran am Rückfluß oder mit Hilfe eines desaktivierten Katalysators (Lindlar-Katalysator), und man erhält das Spiro-C15-Rydroxyacetal X. Die Aufarbeitung erfolgt, wie bei allen vorangegangenen Stufen, in üblicher Weise extraktiv und destillativ im Hochvakuum. The triple bond in IX is selectively hydrogenated to the double bond, for example with lithium alanate in absolute tetrahydrofuran under reflux or with the aid of a deactivated catalyst (Lindlar catalyst), and the spiro-C15-hydroxyacetal X is obtained in all of the preceding stages, in the customary extractive and distillative manner in a high vacuum.
Die Hydrolyse des Acetals X mit wäßriger Säure (beispielsweise p-Toluolsulfon8äure, Essigsäure, Mineralsäuren, vorzugsweise wäßrig/acetonische Salzsäure) unter Luftausschluß liefert den entsprechenden Aldehyd XI, der zweckmäßig säulenchromatographisch gereinigt wird. The hydrolysis of the acetal X with aqueous acid (for example p-toluenesulfonic acid, acetic acid, mineral acids, preferably aqueous / acetonic hydrochloric acid) in the absence of air gives the corresponding aldehyde XI, which is expediently purified by column chromatography.
Den Aldehyd XI unterwirft man schließlich einer Wittig-Synthese mit
3-Methyl-4-(diethylphosphonato )-crotonsäuremethylester oder 3-Methyl-4--triphenylphosphono-crotonsäuremethylester,
um als Endprodukt den Spiroretinsäuremethylester XII zu erhalten. Die Phosphor-Reagentien
werden wahlweise als trans- oder cis-Olefine oder gegebenenfalls als Gemische dieser
beiden eingesetzt Dabei kann zur Erzeugung des Ylids eine Vlelzahl von Deprotonierungsreagentien
eingesetzt werden, beispielsweise Natriushydrid, Lithiumalkyl- und -arylverbindungen,
Natriumamid, Natriummethylat, Lithiumethylat, Lithiumalkylamid.
Die Synthese verläuft also, ausgehend vom käuflichen 2-Methylcyclohexanon, über zehn isolierte Stufen, wobei die nicht-isolierten Zwischenprodukte nicht mitgezählt sind. Unter diesen Umständen sind Gesamtausbeuten über alle Stufen von 0,5 bis 5 X, bezogen auf den genannten Ausgangsstoff, als ausgezeichnet anzusehen.The synthesis therefore proceeds, starting from the commercially available 2-methylcyclohexanone, over ten isolated steps, not counting the non-isolated intermediates are. Under these circumstances there are overall yields across all levels from 0.5 to 5%, based on the starting material mentioned, to be regarded as excellent.
