Article abstract of DOI:10.1016/S0040-4020(01)88221-1

The syntheses of pentasaccharide I and heptasaccharide II, which correspond to an ovarian O-glycoprotein, are presented. The protected pentasaccharide 1 was prepared by condensing a trisaccharide donor (18c) with a disaccharide acceptor (8b), while conden
