✦ Synopsis

The synthesis of glycosides of uronic acids by catalytic air-oxidation of glycosides of the corresponding aldoses has been reviewed by Heyns and Paulsen ~. Methyl ~-and /l-D-gulopyranosiduronic acids• required for a study of lanthanide-induced shifts in the n.m.r, spectra of carbohydrates, may be prepared as their ammonium salts by catalytic air-oxidation of the corresponding, neutral methyl gulosides 2. However, since the methyl ~-and /,~-D-gulosides were not readily available, we now report the preparation of the uronic acid glycosides froni D-glycera-D-gulo-heptose (1),
