An effective procedure for the synthesis of 2-deoxy-2-fluoro-sugar nucleotides via Selectfluor-mediated electrophilic fluorination of glycals with concurrent nucleophilic addition or chemo-enzymatic transformation has been developed. and the fluorinated sugar nucleotides have been used as probes For glycosyltransferases, including fucosyltransferase III, V, VI, and VII, and sialyl transferases. In general, these fluorinated sugar nuclceotides act as competitive inhibitors versus sugar nucleotide substrates and form a tight complex with the glycosyltransferase. (C) 2000 Elsevier Science Ltd.

inhibitors of fucosylation have shown promise as therapeutic agents for sickle cell disease, arthritis, and cancer. We describe here the design and synthesis of a panel of fluorinated l-fucose analogs bearing fluorine atoms at the C2 and/or C6 positions of l-fucose as metabolic fucosylation inhibitors. Preliminary study of their effects on cell proliferation revealed that the 6,6-difluoro-l-fucose (3) and
