1,2-trans-2-Nitro-, 4-nitro- and 2,4-dinitrophenyl-1-thioglycopyranosides were synthesized in high yield by condensation of per-O-acetyl-1-thioglucose with the appropriate nitro- or dinitrofluorobenzene in the presence of potassium carbonate. The pseudothiourea precursor was also used under these coupling conditions. 1,2-trans-4-Nitrophenyl-1-thioglycosides derived from β-D-galactose, β-D-xylose, α-L-arabinose and maltose were also obtained in good yield.
