Abstract

L'invention concerne un procédé pour produire un polysaccharide désulfaté par réaction d'un polysaccharide sulfaté contenant un saccharide possédant des groupes hydroxyle primaires sulfatés comme constituant sucre avec un agent de silylation représenté par la formule générale (I) dans laquelle les trois R<1> représentent chacun indépendamment hydrogène ou halogène; R<2> représente alkyle inférieur; et les trois R<3> représentent chacun indépendamment alkyle inférieur, aryle ou halogène. L'invention concerne également une héparine désulfatée produite au moyen de ce procédé.
