A series of fluorous-tagged saccharide primers with different contents of fluorous atoms was synthesized and introduced into mouse melanoma B16 cells. The primers did not affect cell morphology and viability at a concentration of 50 µM. The numerous fluorine atoms did not pose a steric barrier to primer assimilation into cells and did not affect cellular-enzyme-catalyzed glycosylation. The lactoside primers were sialylated to afford GM3-type oligosaccharide. On the other hand, the GlcNAc primers were galactosylated to afford a lactosamine derivative that was further sialylated by cellular enzymes to afford a sialylated lactosamine.
