Description
Verfahren zur Herstellung von Amiden bzw. substituierten Amiden von Aminosäuren oder Peptiden Die vorliegende Erfindung betrifft ein Verfahren zur Herstellung von Amiden bzw. substituierten Amiden von Aminosäuren bzw. Peptiden. Derartige Verbindungen haben nicht nur als Zwischenprodukte, sondern auch als wirksame Heilmittel Bedeutung.Process for the preparation of amides or substituted amides of Amino acids or peptides The present invention relates to a method of preparation of amides or substituted amides of amino acids or peptides. Such connections are important not only as intermediates, but also as effective remedies.
Das übliche Verfahren zur Synthese von Aminosäureamiden bzw. Peptidamiden besteht in der Umsetzung von Halogeniden der zugrunde liegenden Säuren mit Ammoniak bzw. Aminen. Diese Halogenide sind häufig nicht rein darzustellen, z. B. zerfallen die Chloride carbobenzoxylierter Aminosäuren unter Abspaltung von Benzylchlorid in innere Anhydride.The usual method for the synthesis of amino acid amides or peptide amides consists in the conversion of halides of the underlying acids with ammonia or amines. These halides can often not be presented in pure form, e.g. B. disintegrate the chlorides of carbobenzoxylated amino acids with elimination of benzyl chloride into internal anhydrides.
Ein anderer Weg zur Gewinnung von Amiden führt über die Ester, die mit Ammoniak bzw. Aminen umgesetzt werden. Dieses Verfahren hat besonders bei empfindlichen Peptiden den Nachteil, daß dabei eine Umamidierung oder gar ein Zerfall eintreten kann.Another way of obtaining amides is via the esters, which be reacted with ammonia or amines. This procedure is especially useful for sensitive people Peptides have the disadvantage that transamidation or even disintegration occur can.
Es wurde nun gefunden, daß man, ausgehend von Aminosäuren bzw. Peptiden, zu den gewünschten Amiden gelangt, wenn man Anhydride der allgemeinen Formel die aus Aminosäuren oder Peptiden und einer beliebigen Carbonsäure erhalten wurden, mit Ammoni: k. oder. Aminoverbindungen der allgemeinen Formel H N durch Zugabe der berechneten Menge Base, zu Säurederivaten der allgemeinen Formel umsetzt. In den oben stehenden Formeln bedeuten R einen _#,lkyl-, Acyl- oder einen anderen, zum Schutz einer Aminogruppe geeigneten, nachträglich wieder leicht abspaltbaren Rest, X einen beliebigen organischen Rest, wie er in Aminosäuren oder Peptiden vorhanden ist, Y i Wasserstoffatom, i Alkyl-. Aryl-, Aralkyl- oder ähnliche Gruppe, Z und Z' i Wasserstoffatom oder einen an der reagierenden Aminogruppe befindlichen organischen Rest.It has now been found that, starting from amino acids or peptides, the desired amides can be obtained if anhydrides of the general formula are used obtained from amino acids or peptides and any carboxylic acid, with ammonia: k. or. Amino compounds of the general formula H N by adding the calculated amount of base to acid derivatives of the general formula implements. In the above formulas, R denotes a _ #, alkyl, acyl or other radical which is suitable for protecting an amino group and which can subsequently be easily split off again, X any organic radical as it is present in amino acids or peptides, Y i hydrogen atom , i alkyl-. Aryl, aralkyl or similar group, Z and Z 'i hydrogen atom or an organic radical located on the reacting amino group.
Gegenstand des Patents 8:I0 243 ist ein Verfahren zur Herstellung von Peptiden, wobei Anhydride der vorstehend erwähnten Art mit Amytiosäuren, niedriger molekularen Peptiden bzw. deren Estern durch Zugabe der berechneten Menge Base zu Peptiden umgesetzt werden. Dieses Verfahren ist nicht Gegenstand der vorliegenden Erfindung.The subject of patent 8: I0 243 is a method for production of peptides, with anhydrides of the type mentioned above with amytio acids, lower molecular peptides or their esters by adding the calculated amount of base Peptides are implemented. This procedure is not the subject of the present Invention.
Bei der Umsetzung der erfindungsgemäß verwendeten Anhydride mit Ammoniak oder mit beliebigen Aminoverbindungen gemäß dem Verfahren der vorliegenden Erfindung entstehen in Gegenwart von Basen die gewünschten Amide sowie das Salz der den betreffenden Anhvdriden zugrunde liegenden anderen Carbonsäure nach folgender lteaktionsgleichung: Die Herstellung der erfindungsgemäß verwendeten Anhydride erfolgt, wie in der obenerwähnten älteren Patentschrift angegeben.When the anhydrides used according to the invention are reacted with ammonia or with any amino compounds according to the process of the present invention, the desired amides and the salt of the other carboxylic acid on which the anhydride in question is based are formed in the presence of bases according to the following reaction equation: The anhydrides used according to the invention are prepared as indicated in the earlier patent mentioned above.
Bei der Durchführung des erfindungsgemäßen Verfahrens ist es nicht notwendig, in jedem Fall das Anhydrid zu isolieren. Man kann auch das in wasserfreiem Medium erzeugte Änhydrid direkt mit Ammoniak oder der Lösung einer Aminoverbindung umsetzen.When carrying out the method according to the invention, it is not necessary to isolate the anhydride in each case. One can also do that in anhydrous Medium generated anhydride directly with ammonia or the solution of an amino compound realize.
Das erfindungsgemäße Verfahren weist zahlreiche Vorteile gegenüber den bekannten Darstellungsweisen für Amide auf, insbesondere fällt die Herstellung der labilen Aminosäurechloride fort. Für die Durchführung der Reaktion ist kein Erwärmen notwendig. Die Bedingungen sind so milde, daß auch empfindliche Komponenten Verwendung finden können.The method according to the invention has numerous advantages over this the known modes of presentation for amides, in particular the production falls of the labile amino acid chlorides. There is no for carrying out the reaction Warming necessary. The conditions are so mild that even sensitive components Can be used.
Das erfindungsgemäße Verfahren soll im folgenden an Hand von einigen Ausführungsbeispielen näher erläutert werden.The method according to the invention is intended below with reference to a few Embodiments are explained in more detail.
