Base-catalysed glycoside cleavage

Figure 3.34 Some pathways for base-catalysed glycoside cleavage not involving reaction at the anomeric centre. Figure 3.34 Some pathways for base-catalysed glycoside cleavage not involving reaction at the anomeric centre.
The possibility of effecting selective cleavage of glycosidic linkages in partially methylated polysaccharides by oxidation of the unsubstituted hydroxy-groups and base-catalysed /3-elimination from the oxidized product (see Vol. 6, pp. 116 and 157) has been tested with the methylated disaccharide (20). The results... [Pg.18]

The cleavage of polysaccharides by hydrolysis with acid, by oxidation with periodate or chromium trioxide, by base-catalysed jS-elimination, by deamination, and by Weermann and Lossen rearrangements has been ably reviewed. A new approach to selective cleavage of the glycosidic bond to the reducing-end residue of oligosaccharides has involved base-catalysed j8-elimination on a model 5-deoxy-5-nitromaltitol derivative. ... [Pg.431]
