Synthesis of the β-1,3-glucan, laminarahexaose: NMR and conformational studies

The synthesis of laminarahexaose is described. NMR studies of several of the intermediates leading to the β-1,3-glucan show anomalously small coupling constants for some of the C-1 hydrogens. An X-ray structure for the protected hexasaccharide shows that

Method for synthesis of beta glucans

The invention provides a method for forming P-glucoside linkages in carbohydrate polymers, particularly synthetic glucan molecules, by attaching a protecting group to the C2 position of a glucoside donor. The protecting group of the invention stabilizes t
