Homochiral D- and L-hexose precursors have been prepared in good overall yield from (R)-methyl-p-tolysulfoxide as the sole asymmetric inductor. The process involves sequential condensation of the sulfoxide with ethyl 2-furancarboxylate, stereoselective sulfoxide-monitored carbonyl reduction, Pummerer rearrangement of the sulfinyl group, reduction of the resulting aldehydes and ring-oxidation of the corresponding furfuryl alcohols.
