Description
Verfahren zur Herstellung eines Choladiens. Das vorliegende Patent betrifft ein Ver fahren zur Herstellung eines Choladiens, wel ches dadurch gekennzeichnet ist, dass man eine Verbindung der Formel
EMI0001.0004
worin R einen durch Hydrolyse in die Oxy- gruppe überführbaren Rest, wie eine Acyloxy- gruppe, darstellt, mit einem Carbonsäure- derivat, das den Rest
EMI0001.0012
ent hält, unter Belichtung behandelt,
anschlie ssend aus der erhaltenen Verbindung Halogen wasserstoff abspaltet und die Reste R mit hydrolysierenden Mitteln in Oxydgruppen überführt.
Das so erhaltene d2o.23-3,12-Dioxy-24,24-di- phenyl-choladien ist. neu. Es schmilzt bei 1240 und soll als Zwischenprodukt Verwendung finden.
Als Carbonsäurederivate, die den Rest
EMI0001.0019
enthalten, verwendet man zum Beispiel N-Halogen-succinimide, -phthal- imide, -parabansäuren, -cyanursäuren, -hydan- toine oder -barbitursäuren, ferner entspre chende Derivate von primären oder sekun dären Carbonsäureamiden, wie von Acetamid, Propionamid oder Diacetamid, oder von Car- bonsäurearyl-amiden, z.
B. von kernhaloge- nierten oder -nitrierten Acetaniliden und 3s Benzaniliden. Bei der Halogenierung arbeitet man zweckmässig in inerten Lösungs- bzw. Verdünnungsmitteln, -wie Tetrachlorkohlen- stoff, Chloroform, Benzol, Cyclohexan, Me- tliylcyclohexan,
Äthyläther oder Dioxan. Für 40 die Belichtung können verschiedene Licht quellen mit und ohne ultravioletten Anteil verwendet werden, wie z. B. Licht von Glüh lampen, Quarzlampen, Bogenlampen, aber auch starkes natürliches Licht, wie direktes 45 Sonnenlicht. Die Abspaltung von Halogen wasserstoff unter Bildung einer Doppelbin dung in 20,22-Stellung wird zum Beispiel durch Behandeln mit Halogenwasserstoff ab spaltenden Mitteln oder aber durch Erhitzen so durchgeführt.
<I>Beispiel:</I> Man übergiesst 100 Gewichtsteile 423-3,12- Diacetoxy-24,24-diphenyl-cholen und 30 Ge wichtsteile N-Brom-succinimid mit 1000 Vo- 5s lumteilen reinem Tetrachlorkohlenstoff und erhitzt unter starker Bestrahlung am Rück flusskühler (mit Calcium-chlorid-Verschluss) zum Sieden. Nach kurzem Kochen entwickelt sich Bromwasserstoff. Das Reaktionsgemisch so wird ungefähr 4 weitere Stunden bis zum Aufhören der Bromwasserstoffentwicklung erhitzt.
Nach dem Abkühlen putscht man das Succinimid ab, dampft das Filtrat ein und löst den Rückstand in Aceton auf, wobei das 6s <B>,120,23-3,12</B> -Diacetoxy-24,24-diphenyl-choladien auskristallisiert (75,4 Gewichtsteile). Das aus Aceton umkristallisierte reinste Dien-diacetat schmilzt bei 144 bis 1461 und erstarrt dann wieder zu kleinen Nadeln, -um erneut und end gültig bei 1840 zu schmelzen.
Die eingedampf- ten Mutterlaugen werden mit 30 Volumteilen Dimethylanilin 10 Minuten lang gekocht, die abgekühlte Lösung dann mit Äther verdünnt und das Dimethylanilin durch Ausschütteln mit Salzsäure und Wasser entfernt.
Die äthe rische Lösung wird hierauf mit Natriumsul fat getrocknet, eingedampft und der Rück stand eine Stunde auf dem Wasserbad mit 50 Volumteilen Pyridin und 30 Voluunteilen Acetanhydrid reacetyliert. Nach dem Ein dampfen der Lösung im Vakuum nimmt man das zurückbleibende Öl in Äther auf, wäscht die ätherische Lösung mit Salzsäure und Wasser, trocknet und dampft sie ein.
Aus Aceton und etwas Wasser kristallisieren wei tere 6,4 Gewichtsteile des Dien-diacetats. Die totale Ausbeute beträgt somit 821/o der Theo rie.
Zwecks vollständiger Verseifung werden 10 Gewichtsteile des erhaltenen Dien-diacetats vom F. 144 bis 1460 bzw. 1840 mit 4 Gewichts teilen Kaliumhydroxyd in 250 Voliunteilen wässerigem Äthanol 2 Stunden -unter Rück fluss erhitzt. Man dampft hierauf die Reak tionslösung im Vakuum ein und nimmt den Rückstand in Äther auf. Die mit Wasser ge waschene und mit Natriumsulfat getrocknete ätherische Lösung wird mit etwas Kohle be handelt und dann durch eine mit wenig Alu- miniiunoxyd gefüllte Säule fliessen gelassen.
Der Rückstand der eingedampften Lösung kristallisiert aus Methanol in feinen wasser- haltigen Nadeln. Das so erhaltene 420.23-3,1.2- Dioxy-24,24-diphenylcholadien schmilzt un scharf bei 1240.
Process for the production of a choladiene. The present patent relates to a process for the preparation of a choladiene, wel Ches is characterized in that a compound of the formula
EMI0001.0004
where R represents a radical which can be converted into the oxy group by hydrolysis, such as an acyloxy group, with a carboxylic acid derivative which represents the radical
EMI0001.0012
contains, treated under exposure,
then splitting off hydrogen from the compound obtained and converting the radicals R into oxide groups using hydrolyzing agents.
The d2o.23-3,12-dioxy-24,24-diphenylcholadiene thus obtained is. New. It melts at 1240 and is said to be used as an intermediate.
As carboxylic acid derivatives that make up the rest
EMI0001.0019
contain, one uses, for example, N-halosuccinimide, phthalimide, parabanic acids, cyanuric acids, hydantoin or barbituric acids, as well as corresponding derivatives of primary or secondary carboxamides, such as acetamide, propionamide or diacetamide, or of carboxylic aryl amides, e.g.
B. of nuclear halogenated or -nitrated acetanilides and 3s benzanilides. In the case of halogenation, it is expedient to work in inert solvents or diluents, such as carbon tetrachloride, chloroform, benzene, cyclohexane, methylcyclohexane,
Ethyl ether or dioxane. Various light sources with and without an ultraviolet component can be used for the exposure, such as. B. Light from incandescent lamps, quartz lamps, arc lamps, but also strong natural light such as direct sunlight. The splitting off of hydrogen halide with the formation of a double bond in the 20,22 position is carried out, for example, by treatment with agents which split off hydrogen halide or by heating.
<I> Example: </I> 100 parts by weight of 423-3,12-diacetoxy-24,24-diphenylcholen and 30 parts by weight of N-bromosuccinimide are poured over with 1000 parts by weight of pure carbon tetrachloride and heated under strong irradiation at the reflux condenser (with calcium chloride cap) to boiling. After a short boil, hydrogen bromide develops. The reaction mixture is heated for about 4 more hours until the evolution of hydrogen bromide ceases.
After cooling, the succinimide is popped off, the filtrate is evaporated and the residue is dissolved in acetone, the 6s, 120,23-3,12 -diacetoxy-24,24-diphenylcholadiene crystallizing out (75.4 parts by weight). The purest diene diacetate recrystallized from acetone melts at 144 to 1461 and then solidifies again to small needles - only to melt again and finally at 1840.
The evaporated mother liquors are boiled with 30 parts by volume of dimethylaniline for 10 minutes, the cooled solution is then diluted with ether and the dimethylaniline is removed by shaking with hydrochloric acid and water.
The ethereal solution is then dried with sodium sulfate, evaporated and the residue was reacetylated for one hour on the water bath with 50 parts by volume of pyridine and 30 parts by volume of acetic anhydride. After evaporating the solution in a vacuum, the remaining oil is taken up in ether, the ethereal solution is washed with hydrochloric acid and water, dried and evaporated.
Further 6.4 parts by weight of the diene diacetate crystallize from acetone and a little water. The total yield is thus 821 / o of theory.
For complete saponification, 10 parts by weight of the diene diacetate obtained, having a melting point of 144 to 1460 or 1840 with 4 parts by weight of potassium hydroxide in 250 parts by volume of aqueous ethanol, are heated under reflux for 2 hours. The reaction solution is then evaporated in vacuo and the residue is taken up in ether. The ethereal solution, washed with water and dried with sodium sulphate, is treated with a little charcoal and then allowed to flow through a column filled with a little aluminum oxide.
The residue of the evaporated solution crystallizes from methanol in fine water-containing needles. The 420.23-3,1.2-dioxy-24,24-diphenylcholadiene obtained in this way melts un sharply at 1240.
