Abstract: Unlike other -mannopyranoside-2-sulphonates, the 2-O-trifluoromethylsulfonyl (trifluoromethanesulfonate) derivative, (II), underwent an S_N2 displacement with an azide ion to give methyl (2'R,3'R)-2-azido-2,6-dideoxy-3,4-O-(2',3'-dimethoxybutane-2',3'-diyl)--L-glucopyranoside, C₁₃H₂₃N₃O₆, (IV), in preference to the E2 reaction.
