Abstract: Anomerization of methyl-hepta-0-acetyl-β -maltoside with titanium tetrachloride followed by deacetylation gave methyl-α-maltoside and methyl-β-maltoside in the ratio 7 : 1 . Reaction of maltose with methanol under catalytic action of ion-exchanger Amberlite IR-120 led to the formation of methyl-α,D-glucoside as the main product, and small amounts of methyl-β-maltoside and methyl-α-maltoside in the ratio 3 : 1 . Methyl - -α-maltoside was separated from the β-anomer by ion-exchange chromatography on Dowex 1.
