A simple stereospecific route to 5-C-alkoxy-D-galactopyranosides and to L-arabino-hexos-5-uloses

5-C-alkoxy-β-D-galactopyranosides, which are easily convertible into L-arabino-hexos-5-uloses, can be prepared from β-D-galactopyranoside via peroxyacid oxidation in an alcoholic solvent of intermediate 4-deoxy-α-L-threo-hex-4-enopyranosides.

Preparation of L-lyxo-hexos-5-ulose through C-3 epimerization of bis-glycopyranosides of L-arabino-hexos-5-ulose 1

The unreported title compound and its 2,6-di-O-benzyl derivative have been prepared from methyl β-D-galactopyranoside through a sequence involving the bisglycoside methyl 2,6-di-O-benzyl-5-C-methoxy-β-D-galactopyranoside 8, the precursor of L-arabino-hexo

NEW SYNTHETIC PATHWAYS TO 5-C-ALKOXYPYRANOSIDES AND TO HEXOS-5-ULOSE DERIVATIVES

Several new 5-C-alkoxy-D-galactopyranosides have been obtained by oxidation of 4-deoxy-α-L-threo-hex-4-enopyranosides (easily available from β-D-galactopyranosides) with MCPBA in alcoholic solvents.They have been converted into the so far unreported L-ara
