ABSTRACT:
Disaccharides of formula (I) are derived from a-maltosyl fluoride, wherein R1and R2are 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.
