Verfahren zur Herstellung von Hydrohalogeniden von AminodicarbonsäureanhydridenProcess for the preparation of hydrohalides of aminodicarboxylic acid anhydrides
Die Erfindung befasst sich mit einem Verfahren zur Herstellung von Hydrohalogeniden von Aminodicarbonsäureanhydriden. Insbesondere betrifft die Erfindung ein verbessertes Verfahren zur Herstellung von Hydrohalogeniden von Asparaginsäure- oder Glutaminsäureanhydrid durch Kontaktierung der entsprechenden Aminodicarbonsäure mit einem halogenierten Dehydratisierungsmittel in einem inerten, organischen Lösungsmittel.The invention is concerned with a process for the preparation of hydrohalides of aminodicarboxylic acid anhydrides. In particular, the invention relates to an improved process for the preparation of hydrohalides of aspartic or glutamic anhydride by contacting the corresponding aminodicarboxylic acid with a halogenated dehydrating agent in an inert organic solvent.
Die Hydrohalogenide von Aminodicarbonsäureanhydriden können als chemische Zwischenprodukte zur Herstellung verschiedener Derivate der entsprechenden Aminosäuren, beispielsweise Peptid- und Ester-Derivaten verwendet wer-The hydrohalides of aminodicarboxylic anhydrides can be used as chemical intermediates in their manufacture various derivatives of the corresponding amino acids, for example peptide and ester derivatives, are used

den (J.A.C.S., 8J>, 1839 (1963)). Die Hydrohalogenide der Anhydride sind auch bekannte Zusätze zur Verbesserung des Aromas von Nahrungsmitteln (niederländische Patentveröffentlichung 650 4 992). Sie wurden bisher durch Kontaktierung der Aminosäuren mit einem grossen Überschuss eines Dehydratisierungsmittels in einem stark-sauren Medium, wie Trifluoressigsäure, das nur schwierig zu handhaben ist, hergestellt, wozu auf die britische Patentschrift 1 096 verwiesen wird.den (J.A.C.S., 8J>, 1839 (1963)). The hydrohalides of Anhydrides are also known additives to improve the flavor of food (Dutch patent publication 650 4 992). They were previously made by contacting the amino acids with a large excess of one Dehydrating agent in a strongly acidic medium, such as trifluoroacetic acid, which is difficult to handle, manufactured, for which reference is made to British patent specification 1,096.
Bei dem bekannten Verfahren lassen sich die Hydrohalogenide der Aminosäureanhydride nicht leicht isolieren und werden gewöhnlich als ölartige Substanzen erhalten, die mit den als Umsetzungsmedium verwendeten starken Säuren verunreinigt sind. Wenn deshalb diese Salze der Aminosäureanhydride als chemische Zwischenprodukte verwendet werden, hemmen die in den Salzen enthaltenen starken Säuren die Umsetzungen, beispielsweise die Peptidbildungsreaktion und die Amidbildungsreaktion.In the known process, the hydrohalides of the amino acid anhydrides cannot easily be isolated and are usually obtained as oil-like substances that react with the strong acids used as the reaction medium are contaminated. Therefore, when these salts of amino acid anhydrides are used as chemical intermediates, the strong acids contained in the salts inhibit the Conversions, for example the peptide formation reaction and the amide formation reaction.
Es wurde jetzt festgestellt, dass die Aminodicarbonsäuren, insbesondere Asparaginsäure und Glutaminsäure, leicht mit halogenhaltigen Dehydratisierungsmitteln in inerten, organischen Lösungsmitteln dehydratisiert werden können und die Hydrohalogenide der entsprechenden Aminosäureanhydride praktisch quantitativ ergeben. Es wurde weiterhin festgestellt, dass die gemäss der Erfindung gebildeten Hydrohalogenide der Anhydride leicht in reinem Zustand isoliert werden können.It has now been established that the aminodicarboxylic acids, especially aspartic acid and glutamic acid, easily in with halogen-containing dehydrating agents inert organic solvents are dehydrated can and give the hydrohalides of the corresponding amino acid anhydrides practically quantitatively. It was furthermore found that the hydrohalides of the anhydrides formed according to the invention easily in pure State can be isolated.
Gemäss der Erfindung werden die Aminodicarbonsäuren mit halogenhaltigen Dehydratisierungsmitteln in organischen Lösungsmitteln, die gegenüber den Reaktionsteilnehmern und den Produkten inert sind, kontaktiert. Die Dehydrabisierungsmittel werden üblicherweise in Mengen vcn nicht weniger als 0,3 Mol, vorzugsweise 0,5 bis 6 MolAccording to the invention, the aminodicarboxylic acids with halogen-containing dehydrating agents are in organic Solvents that are inert to the reactants and the products contacted. The dehydrating agents are usually used in amounts of not less than 0.3 mol, preferably 0.5 to 6 mol

Auch die Säuresalze der Aminodicarbonsäuren, beispielsweise Asparaginhydrochlorid, werden entsprechend dem erfindungsgemässen Verfahren dehydratisiert. Dabei ist jedoch die Ausbeute an dem gewünschten Produkt nicht besonders gut und etwas niedriger als im Fall der Anwendung der entsprechenden freien Aminosäuren als Ausgangsmaterial. The acid salts of the aminodicarboxylic acids, for example asparagine hydrochloride, are also used accordingly dehydrated by the process according to the invention. Included however, the yield of the desired product is not particularly good and somewhat lower than in the case of application the corresponding free amino acids as starting material.
Die Dehydratisierungsreaktion wird üblicherweise durchgeführt, indem ein Dehydratisierungsmittel zu der Lösung oder Suspension der Aminodicarbonsäure, vorzugsweise unter Kühren, zugegeben wird. Auch kann die Umsetzung durchgeführt werden, indem die Aminodicarbonsäure zu einer Lösung des Dehydratisierungsmittels zugegeben wird oder eine Lösung des Dehydratisierungsmittels mit einer Lösung oder Suspension der Aminodicarbonsäure vermischt wird.The dehydration reaction is usually carried out by adding a dehydrating agent to the Solution or suspension of the aminodicarboxylic acid, preferably with stirring, is added. Also can implementation be carried out by adding the aminodicarboxylic acid to a solution of the dehydrating agent or a solution of the dehydrating agent is mixed with a solution or suspension of the aminodicarboxylic acid will.
Die Reaktion verläuft glatt selbst bei Raumtemperatur, kann Jedoch durch Erhitzen des Reaktionsgemisches beschleunigt werden. Reaktionstemperaturen unterhalb 80° C, vorzugsweise von -20° C bis 60° C, werden normalerweise gewählt.The reaction proceeds smoothly even at room temperature, but it can be accelerated by heating the reaction mixture will. Reaction temperatures below 80 ° C, preferably from -20 ° C to 60 ° C, are normally chosen.
Das gewünschte Hydrohalogenid des Aminodicarbonsäureanhydrid wird nach beendeter Umsetzung in Form von Kristallen, die im Reakti ons gemisch suspendiert sind, erhalten und kann leicht nach üblichen Verfahren, wie Filtration, Zentrifugation und Dekantation gesammelt werden. Falls ein gasförmiges Dehydratisierungsmittel verwendet wurde, kann das Additionsprodukt durch Abdampfen des Lösungsmittels der Mutterlauge und anschliessende Zugabe von aliphatischen Ä'thern, wie Äthyläther oder Petroläther, oder Kohlenwasserstoffen, wie Hexan, Pentan und Isooctan, zu dem Rückstand erhalten werden.The desired hydrohalide of the aminodicarboxylic anhydride is after the reaction has ended in the form of crystals, which are suspended in the reaction mixture ons obtained and can be easily collected by conventional methods such as filtration, centrifugation and decantation. If a gaseous dehydrating agent was used, the addition product can be removed by evaporation of the solvent the mother liquor and subsequent addition of aliphatic ethers, such as ethyl ether or petroleum ether, or hydrocarbons such as hexane, pentane and isooctane can be obtained to the residue.
