Description
Verfahren zur Herstellung eines neuen Esters. Es wurde gefunden, dass man zu neuen Estern gelangen kann, wenn man Dioxyver- bindungen der Stilbenreihe mit anorganischen Veresterungsmitteln umsetzt und gegebenen falls die erhaltenen Ester in Salze überführt.
Als Ausgangsstoffe können beliebige Di- oxyverbindungen der Stilbenreihe Verwen dung finden. Insbesondere seien zum Beispiel genannt: a,,a'-Dialkyl-, -Dialkenyl-, -Dialki- nyl.-, -Alkyl-aryl-oder Diaryl;
4,4'-dioxy- stilbene wie a,ä-Dimethyl-4,4'-dioxystilben, a,a-Diäthyl-4,4'-dioxystilben, a-Methyl-ä- äthyl-4,4'-dioxystilben, a,a'-Diisopropyl-4,4'- dioxystilben, a,ä -Diäthinyl-4,4'-dioxystilben oder a,a'-Diphenyl-4,4'-dioxystilben und a- Äthyl-a'-n-propyl-4,4'-dioxystilben.
Geeignete Veresterungsmittel sind zum Beispiel anorganische Säuren sowie deren Halogenide, Anhydride oder auch Ester wie zum Beispiel Phosphoroxychlorid, Phosphor- pentachlorid, Phosphorpentoxyd, m-Phosphor- säure, Chlorsulfonsäure, Toluolsulfonsäurz-. Die Veresterung wird nach an sich bekannten Methoden vorgenommen, wobei man zweck mässig Kondensationsmittel, wie z.
B. Pyridin, Chinolin und dergleichen verwendet. Man kann aber auch nach der Methode von Schotten-Baumann .arbeiten.
Zur Darstellung von Monoestern können die erhaltenen Diester partiell verseift wer den. Diese Monoester können aber auch durch partielle Veresterung hergestellt werden. Auch gemischte Diester können in an sich bekannter Weise gewonnen werden.
Verfahrensgemäss erhältliche Ester, die noch Säuregruppen besitzen, können gegebe nenfalls in Salze übergeführt werden. Dabei kann man sowohl in Wasser schwer- wie auch leichtlösliche Salze erhalten. Die letz teren haben eine besondere therapeutische Be deutung, da wässerige Lösungen dieser Salze injizierbar sind. Zur Herstellung der Salze kann man anorganische oder organische Mit tel verwenden, die mit Säuren Salze bilden, z.
B. Hydroxyde und Carbonate der Alka- lien, Erdalkalien und des Ammoniums oder auch Amine, wie z. 13. Diäthylamin, Äthylen diamin, Piperidin und dergleichen.
Gegenstand der vorliegenden Erfindung bildet ein Verfahren zur Herstellung eines neuen Esters, welches dadurch gekennzeich net ist, dass man 1 Mol a,ä -Diäthyl-4,4'-di- oxystilben mit wenigstens 2 Mol eines phos- phorylierenden Mittels behandelt.
Der so erhaltene Di-phosphorsäureester bildet ein weisses Pulver. Seine Alkalisalze sind in Wasser leicht löslich. Die neue Ver bindung hat eine Wirkung im Oestrus- und U teruswaehstumstest. Sie soll therapeutische Verwendung finden.
<I>Beispiel:</I> Eine Lösung von 1 Teil a,ä -Diäthyl-4,4'- dioxystilben in 5 Teilen Pyridin wird tropfen weise zu einer stark gekühlten Lösung von 2 Teilen Phosphoroxyehlorid in 5 Teilen Py - ridin gegeben. Die Mischung erstarrt bald zu einem Kristallbrei. Man lässt eine Viertel stunde im Eis und danach eine Stunde bei Zimmertemperatur stehen. Hierauf giesst man die Reaktionsmasse in überschüssige ge sättigte Natriumbicarbonatlösung. Unver brauchtes Ausgangsmaterial wird durch Aus schütteln mit Äther entfernt.
Die wässerige Lösung versetzt man dann mit 2n-Salzsäure und fällt den primären Di-phosphorsäure- ester des a,ä -Diäthyl-4,4'-dioxystilbens als weisses, voluminöses Pulver aus. Durch Um- kristallisieren oder Umfällen lässt sich dieser Ester weiter reinigen. 1 Teil des oben beschriebenen Di-phosphor- säureesters wird in 20 Teilen. Wasser gelöst und mit einer Lösung von ss Teilen Calcium- acetat in 10 Teilen Wasser versetzt.
Das Calciumsalz des a,ä -Diäthyl-4,4'-dioxystil- ben-di-phosphorsäureesters fällt dabei als weisses Pulver aus.
4,28 Teile des oben beschriebenen primä ren I3i-phosphorsäureesters werden in 20 Tei len Wasser gelöst und mit (l,80 Teilen Na triumhydroxyd in 5 Teilen Wasser versetzt. Hierauf wird die Lösung im Vakuum zur Trockne verdampft. Der Riickst@@tnd stellt das wasserlösliche Natriumsalz des oben er wähnten primären Di-phosphorsäureesters dar. Durch U mkristallisieren kann es weiter gereinigt werden.
Process for the preparation of a new ester. It has been found that new esters can be obtained if dioxy compounds of the stilbene series are reacted with inorganic esterifying agents and, if appropriate, the esters obtained are converted into salts.
Any dioxy compounds of the stilbene series can be used as starting materials. The following may be mentioned in particular: a ,, a'-Dialkyl-, -dialkenyl-, -dialki- nyl-, -alkyl-aryl- or diaryl;
4,4'-dioxystilbene such as a, a-dimethyl-4,4'-dioxystilbene, a, a-diethyl-4,4'-dioxystilbene, a-methyl-a-ethyl-4,4'-dioxystilbene, a, a'-diisopropyl-4,4'-dioxystilbene, a, ä -diethinyl-4,4'-dioxystilbene or a, a'-diphenyl-4,4'-dioxystilbene and a-ethyl-a'-n- propyl-4,4'-dioxystilbene.
Suitable esterifying agents are, for example, inorganic acids and their halides, anhydrides or also esters such as phosphorus oxychloride, phosphorus pentachloride, phosphorus pentoxide, m-phosphoric acid, chlorosulfonic acid, toluenesulfonic acid. The esterification is carried out according to methods known per se, using appropriate condensation agents, such as.
Example, pyridine, quinoline and the like are used. But you can also work according to the Schotten-Baumann method.
To prepare monoesters, the diesters obtained can be partially saponified. However, these monoesters can also be produced by partial esterification. Mixed diesters can also be obtained in a manner known per se.
Esters obtainable according to the process which still have acid groups can, if appropriate, be converted into salts. It is possible to obtain salts that are both sparingly soluble in water and readily soluble in water. The latter are of particular therapeutic importance, since aqueous solutions of these salts can be injected. To prepare the salts you can use inorganic or organic With tel, which form salts with acids, for.
B. hydroxides and carbonates of the alkali, alkaline earth and ammonium or amines, such as. 13. Diethylamine, ethylene diamine, piperidine and the like.
The subject matter of the present invention is a process for the preparation of a new ester which is characterized in that 1 mol of α, α-diethyl-4,4′-di-oxystilbene is treated with at least 2 mol of a phosphorylating agent.
The diphosphoric acid ester obtained in this way forms a white powder. Its alkali salts are easily soluble in water. The new connection has an effect in the oestrus and uterine growth test. It should find therapeutic use.
<I> Example: </I> A solution of 1 part of a, a-diethyl-4,4'-dioxystilbene in 5 parts of pyridine is added dropwise to a strongly cooled solution of 2 parts of phosphorus oxychloride in 5 parts of pyridine. The mixture soon solidifies into a crystal paste. It is left to stand in the ice for a quarter of an hour and then at room temperature for an hour. The reaction mass is then poured into excess saturated sodium bicarbonate solution. Unused starting material is removed by shaking with ether.
2N hydrochloric acid is then added to the aqueous solution and the primary diphosphoric acid ester of α, α-diethyl-4,4'-dioxystilbene is precipitated as a white, voluminous powder. This ester can be further purified by recrystallization or reprecipitation. 1 part of the above-described di-phosphoric acid ester is in 20 parts. Dissolved water and mixed with a solution of 1/2 part calcium acetate in 10 parts water.
The calcium salt of the α, α-diethyl-4,4'-dioxystilben-diphosphoric acid ester precipitates as a white powder.
4.28 parts of the primary I3i-phosphoric acid ester described above are dissolved in 20 parts of water and treated with (1.80 parts of sodium hydroxide in 5 parts of water. The solution is then evaporated to dryness in vacuo the water-soluble sodium salt of the primary di-phosphoric acid ester mentioned above. It can be further purified by recrystallization.
