Abstract

A protected derivative of the octose moiety of antibiotic ezomycins A1 and A2, 4-N-benzoyl-1-[methyl 3,7-anhydro-2-O-benzoyl-5-(3-N-benzoylureido)-6-O-benzyl-5-deoxy-β-D-threo-D-allooctofuranos-(1,4)-yluronate]cytosine, has been synthesized from 5-acetamido-6-O-benzyl-5-deoxy-1,2-O-isopropylidene-3-O-methylthiomethyll-β-L-erythro-D-allooctofuranose-(1,4) by a series of reactions involving 23 steps.
