N2  - Instructions are given for preparing the title compounds in reproducibly good yields from the appropriate anomer of methyl 4,6-O-benzylidene-2,3-di-O-tosyl-D-galactopyranoside. The &#945;-anomer is converted into a mixture of the anhydro-&#945;-taloside and anhydro-&#945;- guloside by reaction with sodium methoxide in dimethyl sulfoxide as solvent at room temperature. The &#946;-anomer forms the anhydro-&#946;-taloside under similar conditions but with dioxan as solvent for the reactants.
