The first synthesis of the trisaccharideunit of versipelostatin, a down regulator of grp78, was achieved, utilizing methyl triflate promoted glycosidations of thioethyl glycosyl donors of D-digitoxose and D-cymarose with protected digitoxal. The synthesis was terminated by the preparation of a thioglycoside based on diethyldithionophosphonic acid which is ready for further glycosidations with aglycons
