Human milk oligosaccharides: An enzymatic protection step simplifies the synthesis of 3′- and 6′-O-sialyllactose and their analogues

We describe a chemo-enzymatic synthesis of 3′- and 6′-O-sialyllactose, two trisaccharides occurring in the 'acidic fraction' of the human milk oligosaccharides and endowed with potential antiadhesive activity. The key step is the highly regioselective 6′-
