Glycosylation of primary (3-trifluoroacetamidopropanol) and secondary (methyl 2,3-O-isopropylidene-α-L-rhamnopyranoside) alcohols with phenyl 3,4,6-tri-O-acetyl-2-azido-2-deoxy-1-seleno-α-D-glucopyranoside in the presence of N-iodosuccinimide and trimethylsilyl triflate in diethyl ether afforded the corresponding 2-azido-2-deoxyglu-cosides in rather high yields and with good α-stereoselectivity (α:β = 3−5:1). Similar glycosylation with phenyl 3,4,6-tri-O-acetyl-2-azido-2-deoxy-1-seleno-α-D-manno-pyranoside resulted exclusively in α-linked 2-azido-2-deoxymannosides.
