Solid-Phase Phosphorylation of Polysaccharides by Phosphorus Pentoxide

Phosphorylated derivatives of polysaccharides (PSs) such as water-soluble starch, carboxymethylcellulose, apple pectin, poly(galacturonic acid), alginic acid, poly(mannuronic acid), poly(guluronic acid), chitosan, and arabinogalactan were prepared under mild conditions by solid-phase reactions with P2O5. The phosphorylation reactions featured formation of various types of fragments from mono- and disubstituted monophosphates to disubstituted polyphosphates in the PS phosphates.
