Studies on Aminosugars. XXVIII. Synthesis of β- l -Idopyranosides through the Corresponding 5-Enopyranosides

Methyl 6-deoxy-β-l-idopyranoside (7), methyl 2-amino-2,6-dideoxy-β-l-idopyranoside (13) and methyl 3-amino-3,6-dideoxy-β-l-idopyranoside (28) have been prepared through the corresponding suitably protected 5-enopyranoside precursors in good yields.
