Enolates of carbohydrates, 5. Syntheses of axially methyl-branched pyranosiduloses

The α-C-methylated carbohydrates 3 and 5 are available from the benzoyl- and benzylidene protected 2- and 3-uloses 1a, 2, and 4 by reaction with potassium tert-butoxide/methyl iodide in N,N-dimethylformamide.Under pthe same conditions the 2-O-benzyl-3-ulose 1b yields the enol ether 6a, and the enolone 8 is obtained from the 2-O-benzoyl-3-ulose 7.
