Reactions of nonsymmetrical bidentate linkers having a phthalimidoyl and acid chloride group or a 2-benzothiazole group with α-d-glucoside derivatives and their application for the modification of cellulose

The reaction of ‘active ester’ bidentate cross-linking reagents, phthalimido 4-chloroformylbutanoate (1) and phthalimido 4-(2-benzothiazolyloxycarbonyl)butanoate (2) with several protected d-glucose derivatives is described. These reactions are used to introduce the reactive group into cellulose (filter paper) with the aim of linking proteins and cellulose.
