New Set of Orthogonal Protecting Groups for the Modular Synthesis of Heparan Sulfate Fragments

(Equation Presented) Six strategically chosen monosaccharide building blocks, which are protected by a novel set of four orthogonal protecting groups (Lev, Fmoc, TBDPS, and All), can be employed for the efficient synthesis of the 20 disaccharide moieties
