Abstract
The common route to link quinolinium and pyridinium fluorophores to biomolecules via bromoacetic acid has failed in labeling the disaccharide trehalose with N-methyl-6-oxyquinolinium betaine: the unexpected, extremely high instability of the N-carboxymethyl ester was overcome by direct N-alkylation of the quinoline derivative with trehalose triflate.
