Idraparinux, the fully O-sulfated, O-methylated, heparin-related pentasaccharide possessing selective factor Xa inhibitoryactivity, was prepared by two novel synthetic pathways. Each route was based on a 2+3 block synthesis utilizing the same l-iduronic acid-containing trisaccharide acceptor, which was glycosylated with either a glucuronide disaccharide donor or its non-oxidized precursor. The latter
