Synthese von α.ω‐Oligamiden aus L‐Glutaminsäure und L‐Lysin))

Abstract: Einige Oligamide des Nylon-5.5-Typs mit abwechselnd einer freien Carboxylbzw. Aminogruppe je Monomereneinheit wurden nach den Methoden der Peptidchemie aus Glutaminsaure-und Lysinderivaten synthetisiert. Weiter wurden Polykondensationsversuche rnit Derivaten dieser beiden AminosiIuren unternommen. Die Zersetzungsreaktionen beim Kochen in waI3riger Msung sowie das Verhalten gegeniiber salpetriger SzIure wurden untersucht.Synthetische Polyamidfasern besitzen im Gegensatz zu Wolle und Seide keine polaren Seitengr… Show more

“…Another important application of the copper(II) chelate of diamino carboxylates is the formation of dipeptides 8 (Scheme 2) by condensation (using the mixed anhydride method with ClC(O)OEt) of the free ω-NH 2 group with the carboxylic group of amino acids to give finally (after removal of copper) e. g. N ε -(glycyl)-lysine [64], N ε -(γ-glutamyl)-lysine [65], N δ -(γ-glutamyl)-ornithine [66], N δ -(α-glutamyl)-ornithine [66], N δ -(β -aspartyl)-ornithine [67], N ε -(α-glutamyl)-lysine [68], N ε -(β -aspartyl)-lysine [68].…”

“…In a series of studies an ion exchange resin was applied for the removal of Cu(II) [28, 73 -76, 80]. The method with cyanide was introduced by Zahn [65,71,103], that with EDTA by Kuwata and Watanabe [104] and by Ledger and Stewart [84,105].…”
