SYNTHESES RELATED TO THE 3,7-ANHYDRO-OCTOSE IN THE EZOMYCINS AND THE OCTOSYL ACIDS

Two 3,7-anhydro-octoses, namely, methyl 3,7-anhydro-5,6,8-trideoxy-β-D-allo-octofuranoside and methyl 3,7-anhydro-5,6,8-trideoxy-talo-octofuranoside, have been synthesized.The synthetic sequence includes the preparation of an octose from D-ribose by way o
