This method allows the preparation of the core T-antigen building block using a glycosyl imidate as donor [27]. This transformation can also be achieved using boron trifluoride etherate activation of p-Gal(l —3)-a-GalNAc-imidate and reaction with suitably protected serine or threonine acceptors [29].
