Functionalized polysaccharides

摘要

Functionalised carbohydrates can be obtained if a carbohydrate is caused to react with an epoxy compound which also contains a double carbon-carbon bond, such as allyl glycidyl ether, to form a hydroxyalkenyl derivative of the carbohydrate. This derivative can then be epoxidised to form a hydroxy-epoxyalkyl derivative of the carbohydrate. This epoxyalkyl derivative is particularly suitable for further functionalisation of the carbohydrate. The invention relates both to the processes and to the products obtainable thereby.
