Description
Verfahren zur Darstellung eines neuen Esters der Ogy-stilbenreihe. Es wurde gefunden, dass man zu einem neuen Ester gelangen kann, wenn man a,a'- Diäthyl-4,4'-dioxystilben mit einem pro- pionylierenden Mittel behandelt.
Geeignete propionylierende Mittel sind zum Beispiel die Propionsäure selbst, ihre Halogenide oder Ester mit niederen Alko holen (Umesterung), ihr Anhydrid sowie auch das von ihr abgeleitete Keten.
Die neue Verbindung, das a,ä -Diäthyl- 4,4'-dioxystilben-dipropionat, schmilzt bei 106-107 . Sie zeigt gegenüber den bekann ten hormonal wirksamen Verbindungen ohne Steroid-Charakter eine protrahiertere Wir kung im Oestrus- und Uteruswachstumstest und soll deshalb therapeutische Verwendung finden.
<I>Beispiel:</I> 1 Teil a,a'-Diäthyl-4,4'-dioxystilben wird in 15 Teilen Pyridin und 4 Teilen Propion- säureanhydrid einige Zeit auf 105 erhitzt. Nach dem Erkalten verdünnt man langsam mit 200 Teilen Wasser. Das ausfallende 01 wird in Äther aufgenommen und mit n-Schwefelsäure, Wasser und n/10 Natron lauge gewaschen. Nach Abdestillieren des Äthers erhält man den Dipropionsäureester, der sich durch Umkristallisieren aus verdünn tem Methanol reinigen lässt. F. 106-107 .
Process for the preparation of a new ester of the Ogy stilbene series. It has been found that a new ester can be obtained if a, a'-diethyl-4,4'-dioxystilbene is treated with a propionylating agent.
Suitable propionylating agents are, for example, propionic acid itself, its halides or esters with lower alcohols (transesterification), its anhydride and also the ketene derived from it.
The new compound, the a, ä -diethyl 4,4'-dioxystilbene dipropionate, melts at 106-107. Compared to the known hormonally active compounds without steroid character, it shows a more protracted effect in the oestrus and uterine growth test and should therefore be used therapeutically.
<I> Example: </I> 1 part of a, a'-diethyl-4,4'-dioxystilbene in 15 parts of pyridine and 4 parts of propionic anhydride is heated to 105 for some time. After cooling, it is slowly diluted with 200 parts of water. The precipitated 01 is taken up in ether and washed with n-sulfuric acid, water and n / 10 sodium hydroxide solution. After distilling off the ether, the dipropionic acid ester is obtained, which can be purified by recrystallization from dilute methanol. F. 106-107.
