Fucosylation Employing Modified Donor and Acceptor Substrates

Fucosylation Employing Modified Donor and Acceptor Substrates 

Acceptors with modification of the terminal sugar residue, such as Gal l-4Glc, Gal l-4Glucal and Gal l-4(5-SGlc), open further possibilities for fucosylation [73]. 

Similarly, GDP-L-galactose derivatives functionalized at 0-6 were prepared and studied in transfer reactions [75]. 

N-Acetyl glucosaminyltransferases transfer N-acetyl glucosamine to various oligosaccharide acceptors, e. g the pentasaccharide 

Further sialylation give a sialyl Lewis x-containing hexasaccharide [77].
