Eintopfsynthese ungeschützter anomerer Glykosylthiole in Wasser für Glykan‐Ligationen mit hochfunktionalisierten Zuckern

Abstract: Die chemische Synthese von Oligosaccharid-Konjugaten ist essenziell füre in tieferes Verständnis der Funktionen von Kohlenhydraten. Sie kçnnte durch effektive Methoden der anomeren Ligation von ungeschützten Zuckern in Wasser deutlicherleichtert werden. Hier stellen wir ein leistungsfähiges Protokoll zur Herstellung anomerer Glykosylthiole von komplexen Mono-, Di-, und Oligosacchariden vor.U nter Ausnutzung der Nachbargruppenbeteiligung von 2-Acetamidozuckern erzeugte1,2-Oxazoline wurden durch Zugabe von 1-Thi… Show more

“…Site specific protein modification typically relies on native cysteine (Cys) thiols or chemoselective groups engineered into proteins via site-specific mutations. [10][11][12][13][14][15][16] Highly successful in their own right, these methods are labor-intense and only suited for low-level protein modification (in view of the low frequency of Cys or engineered residues in proteins). In stark contrast, extensive prior art illustrates that reductive amination at lysine (Lys) amines [17][18][19][20][21][22][23][24] is a facile tool and achieves protein modification to a very high degree of surface modification, without apparent detriment to the protein structure or catalytic output (for enzymes).…”
