^[a]Bn = benzyl, Bz = benzoyl, isothiocyanyl sialyl = [methyl (4,7,8,9-tetra-O-acetyl-3-deoxy-5-isothiocyanyl d-glycero-d-galacto-α,β-nonulopyranosid)onate].

^[b]unless otherwise stated all reactions were conducted at -78 °C with 1.2 equiv of acceptor in 2:1 dichloromethane:acetonitrile.

^[c]After glycosylation the crude reaction mixture was acetylated to facilitate purification.
