A novel flexible assembly strategy is described for the modular synthesis of heparin and heparansulfates. The reported strategy uses monomeric buildingblocks to construct the oligosaccharide chain to attain a maximum degree of flexibility. In the assembly, 1-hydroxyl glucosazido- and 1-thio uronic acid donors are combined in a sequential glycosylation protocol using sulfonium triflate activator systems
