  • Functionalised maltosyl fluoride as glycosyl donor in the chemo-enzymatic preparation of ratio of oligo-or polysaccharides
    Patent number: 7087746
    Abstract: Disaccharides of formula (I) are derived from a-maltosyl fluoride, wherein R1 and R2 are defined. Such disaccharides are useful as glycosyl donors in transglycosylation reactions catalyzed by glycoside-hydrolazes or in transfer reactions catalyzed by transglycosylases during the preparation of oligosaccharides or polysaccharides.
