Toward the chemoenzymatic synthesis of heparan sulfate oligosaccharides: Oxidative cleavage of p-nitrophenyl group with ceric ammonium salts, C. Cai, L. Li, C. Harvey, J. Liu, R.J. Linhardt, Tetrahedron Letters, 54, 4471–4474, 2013.
Abstract
We have developed an efficient chemoenzymatic synthesis of heparan sulfate oligosaccharides employing the para-nitrophenyl (p-NP) β-glucuronide as an acceptor compatible with enzymatic elongation and one that significantly simplifies oligosaccharide purification on C-18 resin. Employing ceric ammonium nitrate as oxidative reagent to remove the p-NP group unexpectedly also removed the glucuronic acid residue at the reducing-end, affording a smaller oligosaccharide. The application of ceric ammonium sulfate allowed the removal of the p-NP without concomitant loss of the adjacent glucuronic acid offering a route to longer heparin sulfate oligosaccharide products.;
