3-Amino-2,3-Dideoxy-D-Erythro-Furanose Derivatives

D-xylose has been converted into methyl 3-nitro-2,3-dideoxy-D-erythro-furanoside and several analogs which are modified at the 5-position (5-O-benzoyl, 5-O-trimethylacetyl, the uronic acid and methyl uronate ester). These nitro sugars were conveniently hydrogenated to the corresponding amino sugars 1A-1E. The utility of the trimethylacetyl protecting group has been demonstrated for this sequence of reactions.
