Hydroxyl groups of mono-and polysaccharides can be effectively oxidized
with dimethyl sulfoxide (DMSO)-acid anhydride system (1-3) and the resulting
keto sugars are important in the synthesis of amino, branched-chain and rare sugars(4,5). The author previously reported partial oxidation of vicinal hydroxyl groups of methy1 4,6-0-benzylidene-α-and β-D-glucopyranosides with DMSO and phoshorus pentoxide (P2O5) (6). It would be worth to compare
selectivity of the oxidation of hydroxyl groups in mono-and polysaccharides.
This communication describes partial oxidation of vicinal hydroxyl Groups of
6-O-tritylamylose with DMSO and P2O5 and preparation of aminated amylose.
