Hexopyranosid-3-ulose, methyl 2-bromo

This hypothesis would seem justified62 by the fact that the same reaction performed on the epimeric halide (manno configuration) (34) leads to a mixture containing 60% of the 3,3,4,6-tetraacetate of methyl 2-bromo-2-deoxy-a-D-arafcmo-hexopyranosid-3-ulose 3-hydrate (38) and 20% of l,3,4,6-tetra-0-acetyl-2-0-methyl-/8-D-glucopyranose...
