  Verfahren zur Herstellung von Alkyleniminochinonen
Die Umsetzung von   a,ss-Alkyleniminen    mit Chinonen, welche zwei benachbarte Alkoxygruppen enthalten, ist Gegenstand des Deutschen Patentes Nr. 955 597. Nach Beispiel 4 dieses Patentes entsteht aus etwa äquimolaren Mengen 2,3-Dimethoxy-naph  thochinon-(1,4)    und   Athylenimin    unter Austausch einer Alkoxygruppe gegen einen Basenrest das 2  Methoxy-3-äthylenimino-naphthochinon-(1,      4).    Bei der weiteren Bearbeitung dieser Verbindungsklasse wurde festgestellt, dass auch beide Alkoxygruppen durch Basenreste ersetzt werden können.



   Es wurde gefunden, dass man neue Bis (äthylenimino)-p-chinone der Formel
EMI1.1     
 worin X und Y beliebige, jedoch nicht gegen Aminogruppen austauschbare Substituenten, die auch ringförmig miteinander verbunden sein können, und R Wasserstoff oder einen niedermolekularen Alkylrest bedeutet, enthält, wenn man Chinone der Formel
EMI1.2     
 mit mindestens 2 Mol eines Athylenimins der Formel
EMI1.3     
 umsetzt.



   Als Chinone, die verwendet werden können, seien beispielsweise genannt:   
2,3-Dimethoxy-5 ,6-dimethyl-benzochinon-(1 4),
2,3-Dimethoxy-naphthochinon-(1 4),
2,3-Dimethoxy-5 6,?, 8-tetrahydro-naphtho- chinon-(1 4),         6,7-Dimethoxy-chinolinchinon-(5,8)    und    2,3-Diäthoxy-naphthochinon-(1 4).   



   Als   Äthylenimine,    die mit den genannten Chinonen umgesetzt werden können, sind beispielsweise zu nennen: Äthylenimin, 2-Methyl-äthylenimin und 2,2 Dimethyl-äthylenimin.



   Die als Ausgangsmaterialien verwendeten Chinonderivate werden vorzugsweise in einem Lösungs- oder Verdünnungsmittel mit den   Äthyleniminen    zur Reaktion gebracht. Hierbei haben sich die niedermolekularen aliphatischen Alkohole, z. B. Methanol und Äthanol, gut bewährt. Theoretisch sind auf 1 Mol des Chinons 2 Mol der genannten Äthyleniminverbindung zu verwenden, doch ist die Anwendung eines Basenüberschusses oft vorteilhaft. In den meisten Fällen lässt sich die Reaktionszeit erheblich abkürzen, wenn man das Umsetzungsgemisch zum Sieden erhitzt. Die Verfahrenserzeugnisse, die nach den üblichen Methoden isoliert werden können, sind farbige, kristallisierte Verbindungen und besitzen die Fähigkeit, das Wachstum tierischer Tumorzellen zu hemmen.



   Beispiel 1
21,8 g (0,1 Mol) 2,3-Dimethoxy-naphthochinon (1,4) werden in 300   cm3    Methanol mit 208   cm3    (4 Mol)   Äthylenimin    31/2 Stunden rückfliessend gekocht. Die klare, dunkle Reaktionslösung scheidet beim Erkalten das rohe   2,3-Bis-äthylenimino-naph-      thochinon-(1,4)    aus. Man saugt bei -200 ab, wäscht mit vorgekühltem Alkohol und erhält nach dem Trocknen 18,8 g des Produktes vom Fp.: 157 bis   157,50.    Durch Umkristallisieren aus Alkohol werden 17,7 g reine Verbindung in Form rotbrauner Nadeln vom Fp.:   158-159     erhalten.



   Beispiel 2
21,9 g (0,1 Mol) 6,7-Dimethoxy-chinolinchinon (5,8) werden in 300   cm3    Methanol mit 208   cm3    (4 Mol)   Äthylenimin    30 Minuten lang rückfliessend gekocht. Man kühlt alsdann die dunkle Reaktionslösung   auf -200    ab, wobei sich das rohe 6,7-Bis  äthylenimino-chinolinchinon-(5,8)    ausscheidet, saugt dieses ab und wäscht mit ebenfalls vorgekühltem Äthanol. Es werden 18,9 g erhalten, die man aus Äthanol umkristallisiert. Die dadurch gewonnene reine Verbindung (15,4 g) besteht aus rotbraunen Nadeln vom Zersetzungspunkt   200-201 .      



  
 



  Process for the preparation of alkyleneiminoquinones
The reaction of α, β-alkylenimines with quinones, which contain two adjacent alkoxy groups, is the subject of German Patent No. 955 597. According to Example 4 of this patent, approximately equimolar amounts of 2,3-dimethoxy-naphthoquinone- (1,4 ) and ethyleneimine with exchange of an alkoxy group for a base residue, the 2 methoxy-3-ethyleneimino-naphthoquinone- (1, 4). In the further processing of this class of compounds, it was found that both alkoxy groups can also be replaced by base radicals.



   It has been found that new bis (ethyleneimino) -p-quinones of the formula
EMI1.1
 in which X and Y contain any substituents which, however, cannot be exchanged for amino groups and which can also be linked to one another in the form of a ring, and R is hydrogen or a low molecular weight alkyl radical, if quinones of the formula
EMI1.2
 with at least 2 moles of an ethyleneimine of the formula
EMI1.3
 implements.



   Quinones that can be used include, for example:
2,3-Dimethoxy-5, 6-dimethyl-benzoquinone- (1 4),
2,3-dimethoxy-naphthoquinone- (1 4),
2,3-Dimethoxy-5 6,?, 8-tetrahydro-naphthoquinone- (1 4), 6,7-dimethoxy-quinolinequinone- (5,8) and 2,3-diethoxy-naphthoquinone- (1 4) .



   Examples of ethyleneimines that can be reacted with the quinones mentioned are: ethyleneimine, 2-methylethyleneimine and 2,2 dimethylethyleneimine.



   The quinone derivatives used as starting materials are preferably reacted with the ethyleneimines in a solvent or diluent. Here, the low molecular weight aliphatic alcohols, z. B. methanol and ethanol, well proven. Theoretically, 2 moles of the ethyleneimine compound mentioned should be used for 1 mole of the quinone, but the use of an excess of base is often advantageous. In most cases, the reaction time can be shortened considerably if the reaction mixture is heated to the boil. The products of the process, which can be isolated by the usual methods, are colored, crystallized compounds and have the ability to inhibit the growth of animal tumor cells.



   example 1
21.8 g (0.1 mol) of 2,3-dimethoxynaphthoquinone (1.4) are refluxed for 31/2 hours in 300 cm3 of methanol with 208 cm3 (4 mol) of ethyleneimine. The clear, dark reaction solution separates the crude 2,3-bis-ethylenimino-naphthoquinone- (1,4) on cooling. It is filtered off with suction at -200, washed with pre-cooled alcohol and, after drying, 18.8 g of the product of melting point 157 to 157.50 are obtained. Recrystallization from alcohol gives 17.7 g of pure compound in the form of red-brown needles with a melting point of 158-159.



   Example 2
21.9 g (0.1 mol) 6,7-dimethoxy-quinolinequinone (5.8) are refluxed for 30 minutes in 300 cm3 of methanol with 208 cm3 (4 mol) of ethyleneimine. The dark reaction solution is then cooled to -200, the crude 6,7-bis äthylenimino-quinolinequinone- (5,8) separating out, sucked off and washed with likewise pre-cooled ethanol. 18.9 g are obtained, which are recrystallized from ethanol. The pure compound thus obtained (15.4 g) consists of red-brown needles with a decomposition point of 200-201.
