Negative-ion mass spectrometry of carbohydrates. A mechanistic study of the fragmentation reactions of dideoxy sugars

Hydroxyl group deprotonation of the a and β anomers of methyl 3-O-benzyl-2,6-dideoxy-D-arabino-hexopyranoside (1 and 2) occurs readily in the gas phase to produce the corresponding anions 3 and 4, respectively. Collisionally activated dissociation (CAD) o

Studies of the stereoselective reduction of ketosugar (hexosulose)

The results from the studies of the stereoselective reduction of ketosugar (hexosulose) were reported. Combining our results and those reported in the literature, we summarize the factors in controlling the stereoselective reduction of ketosugars. These findings are valuable in the synthesis of various carbohydrate derivatives.
