By means of a decarboxylative acetoxylation induced by lead tetaacetate and a subsequent nitromethane cyclization reaction, methylated derivatives (1a, 4a, 7a) of three glucuronide-saponins [sakuraso-saponin (1), desacyl-jegosaponin (4), and soyasaponin I (7)] were decomposed selectively at the glucuronide lindage to furnish the methylated genuine aglycones (2,5,8) and scyllonitrocyclitol-oligosides (3,6,9). The oligosides were further converted to scyllo-aminocyclitololigosides (3a, 6a, 9a), thus accomplishing syntheses of aminocyclitol-oligosides by making use of the oligosaccharide moieties in glucuronide-saponins.
