Acyl Derivatives of Aldoses. II. Derivatives of D-glycero-D-galacto-Heptose and D-Galactose
The α and β anomers of hexa-O-benzoyl-D-glycero-D-galacfo-heptose and the penta-0-benzovl-β-D-galactose have been prepared for the first time. Anomerization of the α anomer of these benzoyl derivatives by fusion with zinc chloride and benzoic acid led to a mixture of anomers in which the 1-5 trans a...

| Sumario: | The α and β anomers of hexa-O-benzoyl-D-glycero-D-galacfo-heptose and the penta-0-benzovl-β-D-galactose have been prepared for the first time. Anomerization of the α anomer of these benzoyl derivatives by fusion with zinc chloride and benzoic acid led to a mixture of anomers in which the 1-5 trans anomer widely predominates. A similar behavior of the benzoyl derivatives of D-glycero-D-galacto-heptose and the configurationally related hexose has been shown; but the molecular rotations of the corresponding derivatives differ considerably. © 1962, American Chemical Society.
