Description
Verfahren zur Herstellung von y-Oxocarbonsäureamiden Es wurde gefunden, daß man y-Oxocarbonsäureamide auf einfache Weise herstellen kann, wenn man ungesättigte Lactone der allgemeinen Formel in der R einen Alkylrest bedeutet, mit sekundären Aminoverbindungen umsetzt.Process for the preparation of γ-oxocarboxamides It has been found that γ-oxocarboxamides can be produced in a simple manner if unsaturated lactones of the general formula are used in which R denotes an alkyl radical, is reacted with secondary amino compounds.
Geeignete Lactone sind unter anderem das Angelicalacton oder das Hexen-(3)-olid-(4,1). Man erhält solche Lactone z. B. durch Behandeln der entsprechenden y-Oxocarbonsäuren mit wasserabspaltenden Mitteln.Suitable lactones include angelica lactone or hexen- (3) -olide- (4,1). Such lactones are obtained, for. B. by treating the corresponding γ-oxocarboxylic acids with water-releasing agents.
Als Aminoverbindungen seien u. a. genannt das Dimethyl- und Diäthylamin, die Dipropyl- und Dibutylamine, das Pyrrolidin, Piperidin, Hexamethylenimin und Morpholin, das 2-Methyl-5-äthyl-piperidin, das N-Methylanilin, das N-Methyl-cyclohexylamin, das Piperazin.Amino compounds include: called the dimethyl and diethylamine, the dipropyl and dibutyl amines, pyrrolidine, piperidine, hexamethyleneimine and Morpholine, 2-methyl-5-ethyl-piperidine, N-methylaniline, N-methyl-cyclohexylamine, the piperazine.
Die Umsetzung verläuft im Falle der Verwendung von Hexen-(3)-olid-(4,1) und Dimethylamin als Ausgangsstoffe nach dem folgenden Schema: Man führt die Umsetzung zweckmäßig so aus, daß man die Komponenten für sich oder in indifferenten Lösungsmitteln, wie Alkohol, Benzol oder Dioxan oder Gemischen davon, zusammenbringt, wobei man erforderlichenfalls in Druckgefäßen arbeitet. Die Amide der y-Oxocarbonsäuren bilden sich zuweilen schon bei gewöhnlicher Temperatur genügend rasch; in den meisten Fällen ist Erwärmen, z. B. auf 70 bis 120°C, förderlich.In the case of using hexen- (3) -olide- (4,1) and dimethylamine as starting materials, the reaction proceeds according to the following scheme: The reaction is expediently carried out in such a way that the components are brought together individually or in inert solvents such as alcohol, benzene or dioxane or mixtures thereof, with the process being carried out in pressure vessels if necessary. The amides of the γ-oxocarboxylic acids sometimes form sufficiently quickly even at ordinary temperature; in most cases heating, e.g. B. to 70 to 120 ° C, conducive.
Die auf die beschriebene Weise leicht zugänglich gewordenen y-Oxocarbonsäureamide zeigen zum Teil sehr wertvolle pharmakologische Eigenschaften. Im Gegensatz zu den entsprechenden ketogruppenfreien Carbonsäureamideri wirken sie ähnlich schmerzlindernd, zum Teil bereits in geringeren Dosen, wie das bekannteste Analgetikum, das 1-Phenvl-2,3-dimeth#"l-4-(dimethylamino)-pyrazolon-(5).The γ-oxocarboxamides which have become easily accessible in the manner described some show very valuable pharmacological properties. In contrast to the corresponding keto-group-free carboxamides, they have a similar pain-relieving effect, sometimes even in lower doses, such as the best-known analgesic, 1-phenyl-2,3-dimeth # "l-4- (dimethylamino) pyrazolone- (5).
Nach P. Karrer, Lehrbuch der organischen Chemie, 10. Auflage (1948), S.283, Absatz 4, Satz 2, sollen y-Lactone allgemein durch Ammoniak in die entsprechenden y -Hydroxycarbonsäureamide umgewandelt werden; aus der deutschen Patentschrift 918926 ist es bekannt, daß man durch Umsetzen der als besonders reaktionsfähig geltenden ß-Lactone mit sekundären Aminen die entsprechenden N-substituierten ß-Hydroxysäureamide erhält. In welcher Weise sich ungesättigte y-Lactone der oben angegebenen Formel mit sekundären Aminen umsetzen würden, war bisher unbekannt; es war nicht ohne weiteres zu erwarten, daß die Umsetzung unter Bildung von y-Oxocarbonsäureamiden verlaufen würde, weil man in Analogie zu den obengenannten, bekannten Umsetzungen zwar zunächst mit der Bildung von ß,y-ungesättigten y-Hydroxyverbindungen rechnen konnte, die aber, als Enole, ihrerseits mit den Aminen in anderer Weise hätten reagieren können.According to P. Karrer, Textbook of Organic Chemistry, 10th Edition (1948), p.283, paragraph 4, sentence 2, γ-lactones are generally to be converted into the corresponding γ-hydroxycarboxamides by ammonia; It is known from German patent specification 918926 that the corresponding N-substituted β-hydroxy acid amides are obtained by reacting the ß-lactones which are considered to be particularly reactive with secondary amines. The manner in which unsaturated γ-lactones of the formula given above would react with secondary amines was previously unknown; It was not to be expected without further ado that the reaction would proceed with the formation of γ-oxocarboxamides, because in analogy to the above-mentioned, known reactions, the formation of ß, γ-unsaturated γ-hydroxy compounds could be expected, but the than enols, in turn, could have reacted with the amines in a different way.
Das erfindungsgemäße Verfahren zur Herstellung von y-Oxocarbonsäureamiden ist also neu; überdies liefert es, wie bereits erwähnt, Verbindungen mit unerwarteten, wertvollen Eigenschaften.The process according to the invention for the preparation of γ-oxocarboxamides so is new; moreover, as already mentioned, it provides connections with unexpected, valuable properties.
Die in den Beispielen genannten Teile sind Gewichtsteile.The parts mentioned in the examples are parts by weight.
Beispiel 1 112 Teile Hexen-(3)-olid-(4,1), hergestellt durch Behandeln von y-Oxohexan-carbonsäure-(1) (= Homolävulinsäure) mit wasserabspaltenden Mitteln, werden mit 50 Teilen flüssigem Dimethylamin im geschlossenen Gefäß 5 Stunden auf 90°C erhitzt. Bei der fraktionierten Destillation unter 1 mm Druck erhält man 135 Teile Homolävulinsäuredimethvlamid vom Siedepunkt 98 bis 100g C.Example 1 112 parts of hexen- (3) -olide- (4.1) prepared by treating of y-oxohexane-carboxylic acid- (1) (= homolevulinic acid) with dehydrating agents, are with 50 parts of liquid dimethylamine in a closed vessel for 5 hours 90 ° C heated. Fractional distillation under 1 mm pressure gives 135 Parts of homolevulinic acid dimethvlamide with a boiling point of 98 to 100g C.
Die Verbindung wirkt, im Gegensatz zu den ketogruppenfreien gesättigten Carbonsäureamiden, ähnlich schmerzlindernd wie das 1-Pheny1-2,3-dimethyl-4-(dimethylamino)-pyrazolon-(5).The compound works, in contrast to the keto group-free saturated ones Carboxamides, similarly analgesic as 1-Pheny1-2,3-dimethyl-4- (dimethylamino) -pyrazolon- (5).
Beispiel 2 Zu 56 Teilen Hexen-(3)-olid-(4,1) läßt man unter Stickstoffatmosphäre bei 90'C allmählich 53,5 Teile N-Methylanilin fließen. Man rührt weitere 5 Stunden bei 90°C, worauf man fraktioniert destilliert. Das entstandene Homolävulinsäure-N-methylanilid geht in einer Ausbeute von etwa 55 °%o der ,Theorie unter 0,1 mm Druck bei 137°C über. Es zeigt sedative und analgetische Wirkungen.Example 2 To 56 parts of hexen- (3) -olide- (4.1) are left under a nitrogen atmosphere at 90'C gradually 53.5 parts of N-methylaniline flow. One stirs another 5 hours at 90 ° C., after which it is fractionally distilled. The resulting Homolevulinic acid-N-methylanilide goes in a yield of about 55% o the theory under 0.1 mm pressure at 137 ° C above. It shows sedative and analgesic effects.
Die Verbindung wirkt ähnlich schmerzlindernd wie das 1-Phenyl-2,3-dimethyl-4-(dimethylamino)-pyrazolon-(5) ; die kleinste schmerzstillende Dosis beträgt bei beiden Verbindungen etwa 150 mg; kg. Beispiel 3 Zu 56 Teilen Hexen-(3)-olid-(4,1) läßt man unter Stickstoff bei 90°C allmählich 50 Teile Hexamethylenimin zufließen und rührt dann noch 1 Stunde bei dieser Temperatur weiter. Bei der fraktionierten Destillation unter 0,08 mm Druck erhält man 90 Teile Homolävulinsäurehexamethylenimid vom Siedepunkt 144 bis 148°C. Verwendet man an Stelle von Hexamethylenimin 43 Teile Piperidin, so erhält man 60 Teile HomolävuIinsäurepiperidid vom Siedepunkt 115 bis 120°C unter 0,08 mm Drnck.The compound has a similar pain-relieving effect as 1-phenyl-2,3-dimethyl-4- (dimethylamino) -pyrazolon- (5) ; the smallest analgesic dose for both compounds is around 150 mg; kg. Example 3 The mixture is left to 56 parts of hexen- (3) -olide- (4.1) under nitrogen at 90.degree gradually flow in 50 parts of hexamethyleneimine and then stir for a further hour this temperature continues. With fractional distillation under 0.08 mm pressure 90 parts of homolevulinic acid hexamethyleneimide with a boiling point of 144 to 148 ° C. are obtained. If 43 parts of piperidine are used instead of hexamethyleneimine, 60 are obtained Parts of HomolevuIinsäurepiperidid boiling point 115 to 120 ° C under 0.08 mm pressure.
Die beiden Verbindungen zeigen eine ähnliche schmerzlindernde Wirkung wie die Produkte der Beispiele 1 und 2.The two compounds show a similar analgesic effect like the products of Examples 1 and 2.
