Branched-chain Sugars. XI. Synthesis of 2,3,6-Trideoxy-3-C,4-O-dimethyl-3-nitro-d-arabino-hexopyranose (d-Evernitrose)

Abstract
2,3,6-Trideoxy-3-C, 4-O-dimethyl-3-nitro-d-arabino-hexopyranose was synthesized by the oxidation of methyl α-glycoside of the corresponding 3-amino derivative with m-chloroperbenzoic acid followed by hydrolysis. The 3-amino derivative was synthesized from methyl 4,6-O-benzylidene-2-deoxy-α-d-erythro-hexopyranosid-3-ulose by introduction of the amino-branching function according to the method of Bourgeois, followed by 6-deoxygenation and 4-O-methylation.
