Saturated 2-nitrosugar derivatives (11-20 and 22) are easily synthesized by oxidation with m-CPBA of readily available corresponding 2-aminosugars (1-10 and 21), in excellent yield. Alkyl 4,6-O-benzylidene-2-deoxy-2-nitro-D-hexopyranoides suffer O-alkylation and O-acylation in the usual conditions. These 3-O-acetyl-2-nitrosugar derivatives gave the corresponding 2-nitroalkene derivative, which reacts in situ with nuclephiles in high stereoselectivity.
