Abstract

The reactivity of O-benzylated 1-thio-β-D-galactopyranosides in iodine-promoted methanolysis reactions was shown to correlate with aglycone structure, as expected (R = p.NO2Ph < Ph < Bn < p.MeOPh < Me). The rate of methanolysis could be altered substantially through appropriate choice of promoter (ICl > IBr ~ I2+DDQ > I2), with even the unreactive nitrophenyl thioglycoside undergoing complete reaction in less than 2 minutes in acetonitrile in the presence of ICl.
