Verfahren zur Darstellung von neuen Kondensationsprodukten.
Es wurde gefunden, dass Glyeidsäuren, deren Ester oder Amide bzw. Alkyl-, Aralkyl-und Arylsubstitutionsprodukte letzterer mit Aminen, die in einer Aminogruppe wenigstens ein reaktionsfähiges Wasserstoffatom enthalten, bei höherer Temperatur in der Weise reagieren, dass unter Aufspaltung des Oxydoringes substituierte Oxyaminosäuren bzw. deren Ester oder Amide entstehen. Die Reaktion verläuft nach folgender Gleichung :
EMI1.1
(worin R Wasserstoff, gleiche oder ungleiche Alkyl-, Aralkyl- oder Arylgruppen und X -OH, -OR, -NH2 oder -N (R) 2 bedeuten kann).
Ferner wurde gefunden, dass man bei diesen Reaktionen an Stelle von Aminen mit einer ein reaktionsfähiges Wasserstoffatom enthaltenden Aminogruppe auch Amine mit zwei derartigen Aminogruppen verwenden kann. Die Reaktion verläuft dann so, dass erst die eine Aminogruppe unter Sprengung des Oxydoringes substituierte Oxyamidosäuren bzw. deren Ester oder Amide naeh der obigen Gleichung gibt, die zweite Aminogruppe sodann aber unter Abspaltung von Alkohol oder Ammoniak unter Ring-

Process for the preparation of new condensation products.
It has been found that glyeidic acids, their esters or amides or alkyl, aralkyl and aryl substitution products of the latter with amines which contain at least one reactive hydrogen atom in an amino group react at a higher temperature in such a way that, with splitting of the oxy-ring group, substituted oxyamino acids or their esters or amides are formed. The reaction proceeds according to the following equation:
EMI1.1
(in which R can be hydrogen, identical or different alkyl, aralkyl or aryl groups and X can be -OH, -OR, -NH2 or -N (R) 2).
It has also been found that in these reactions, instead of amines with an amino group containing a reactive hydrogen atom, amines with two such amino groups can also be used. The reaction then proceeds in such a way that only the one amino group gives substituted oxyamido acids or their esters or amides according to the above equation, with splitting of the oxide ring, but the second amino group then with elimination of alcohol or ammonia with ring
