    Description / Table of Contents: Summary From a glucose/glycine reaction mixture acids, esters and lactones were isolated and identified. Sugar degradation products could also be determined as benzimidazole derivatives after reaction witho-phenylenediamine. Results derived from model systems suggested possible reaction pathways leading to some of the isolated substances. A lactic acid ester is formed as a product of an unstableβ-pyranone intermediate. A 3-deoxyhexosone serves as a precursor of two furanolactones.
    Notes: Zusammenfassung Aus einem Glucose/Glycin-Reaktionsgemisch wurden Säuren, Ester und Lactone isoliert und identifiziert. Zuckerumwandlungsprodukte ließen sich auch nach Umsetzung mito-Phenylendiamin als Benzimidazolderivate nachweisen. Die Ergebnisse verschiedener Modellumsetzungen lassen Rückschlüsse auf den Bildungsmechanismus einiger isolierter Reaktionsprodukte zu. So bildet sich ein Milchsäureester über ein labiles Zuckerumwandlungsprodukt. Ein 3-Desoxyoson dient als Vorstufe für zwei Furanolaktone.

    Description / Table of Contents: Summary Amadori compounds obtained from maltose were heated witho-phenylenediamine. The main reaction products were found to be the quinoxalines5b,6b, and7a. From the structures of the quinoxalines, it can be deduced that the deoxyosones2b,3b, and4a are formed from maltose. From the determination of some transformation products, it was found that the degradation of glucose in the presence of propylamine does not proceed exclusively with Amadori compound1a as an intermediate. On heating Amadori compound1d, the furane derivative11a was detected, confirming the formation of4a.
    Notes: Zusammenfassung Amadori-Verbindungen aus Maltose wurden mito-Phenylendiamin umgesetzt. Als wesentliche Reaktionsprodukte konnten die Chinoxaline5b,6b und7a isoliert und identifiziert werden. Die Versuche zeigten, daß bei der Maillard-Reaktion aus Maltose die Substanzen2b,3b und4a als Zwischen-stufen gebildet werden. Durch die Bestimmung von Folgeprodukten ließ sich zeigen, daß der Abbau von Glucose in Gegenwart von Propylamin nicht ausschließlich über das Amadoriprodukt1a erfolgt. Erhitzen der Aminoketose1d führte u. a. zur Bildung des Furanderivates11a, was die Bildung von4a bestätigt.

    Description / Table of Contents: Summary By heating Na-acetyllysine with maltose or lactose, the pyridone8 not known up to now is formed, which is transformed into the lysine derivative9 when the acetyl group is split off. We propose the name maltosine for compound9. In contrast to maltosine, the well-known pyridosine, used in the determination of lysine damage, is an “artificial” product formed during acid protein hydrolysis. From the reaction mixtures of galactosyl isomaltol and an Amadori product of maltose with propylamine, the pyridinium betaines13 and14 can be isolated. They are intermediates in the formation of the pyridone12a.
    Notes: Zusammenfassung Beim Erhitzen von Na-Acetyllysin mit Maltose oder Lactose bildet sich u. a. das bisher nicht bekannte Pyridon8 aus dem nach Abspaltung der Acetylgruppe das Lysinderivat9 erhalten wird. Für die neue Substanz9 schlagen wir die Bezeichnung Maltosin vor. Im Gegensatz zum Maltosin ist das schon früher bekannte und zum Nachweis einer Lysinschädigung herangezogene Pyridosin ein „Kunstprodukt” der sauren Proteinhydrolyse. Aus den Umsetzungsgemischen von Galaktosylisomaltol und eines Amadoriprodukts der Maltose mit Propylamin lassen sich die Pyridiniumbetaine13 und14 isolieren. Sie sind Zwischenprodukte bei der Bildung des Pyridons12a.

    Description / Table of Contents: Zusammenfassung Bei der Umsetzung von Formaldehyd und Acetaldehyd mit Schwefelwasserstoff und Ammoniak entsteht ein Gemischt von Verbindungen, in dem verschiedene schwefelhaltige Heterocyclen enthalten sind. In dem flüchtigen Anteil lassen rich durch Gaschromatographie und Massenspektrometrie u. a. Thialdin (4), Dimethyl-dihydro-dithiazin (5) und in geringerer Menge Dimethyltrithiolan (3) und Methyltrithiolan (2) nachweisen. Die Verbindungen bilden sich such beim Erhitzen von Cystein mit Xylose. Sie sind als mögliche Komponenten im Aroma erhitzten Fleisches von Interesse.
    Notes: Summary A mixture of compounds containing several heterocycles with sulphur is obtained, when formaldehyde and acetaldehyde are treated with hydrogen sulphide and ammonia. The formation of thialdine, dimethyl-dihydro-dithiazine and in smaller quantity of dimethyltrithiolane and methyltrithiolane has been proved by the GC-MS-technic. These compounds are also obtained, when cysteine and xylose are heated together. Such sulphur containing heterocycles are of interest in connection with the aroma of roast meat.
