Simultaneous regioselective 3,6- or 2,6-selective protection of 1-thio-beta- or alpha-D-glucopyranosides is described. The C-3 and C-6 hydroxy groups of the beta-thioglucoside were selectively protected with triisopropylsilyl or tert-butyldiphenylsilyl trifluoromethanesulfonate. The C-2 and C-6 hydroxy groups of the alpha-thioglucoside were selectively protected with tert-butyldiphenylsilyl trifluoromethanesulfonate.
