SYNTHESIS OF CARBON BRIDGED C-DISACCHARIDES

Direct lithiation of the readily available 2-phenylsulfinyl-D-glucal 2 provides the 1-C-lithiated species 2A furnishing with 4-deoxy-4-formyl-D-glucose derivative 7 in a diastereocontrolled reaction the C-disaccharide intermediate 8.This compound is trans
