Zusammenfassung
Sugar melts or solvent-free systems have been used to react simple unprotected hexoses at the C-1 atom with urea and urea derivatives to sugar-ureides by acid catalysis and with short reaction times. In one step, β-D-glucosyl- and β-D-mannosyl urea 2a/b were obtained in high yields. D-Galactose 6, N-acetyl-D-glucosamine 7, L-rhamnose 8 and 2-deoxy-D-glucose 9 were converted likewise to glycosyl ...
