A New Synthesis of Methyl 3-Amino-3,4-dideoxy-β-D-xylo- hexopyranoside.

Abstract Benzylidenation of methyl β-D-glucopyranoside, followed by selective 3-O-tosylation, reductive acetal opening, chlorination, radical deoxygenation and transesterification, afforded methyl 2,3-anhydro-6-O-benzyl-4-deoxy-β-D-ribo-hexopyranoside 8. Subsequent epoxide opening with NaN3 and catalytic hydrogenation led to the title compound.
