Abstract
1,2,3,4-Tetra-O-acetyl-β-d-mannuronic acid was synthesized in three steps from commercial d-mannose in 21% yield. Regioselective 6-O-tritylation followed by per-acetylation and 6-OTr removal using HBr/AcOH gave the required primary alcohol substrate, which was then oxidised to the target compound using TEMPO/BAIB. None of the synthetic steps required column chromatography and the product was fully characterized by 1H-NMR, 13C-NMR, 2D NMR, MS and IR.
