A new glycosylation methodology for synthesizing a protected TF antigen is described. The key step is to use phenyl selenoglycoside as a glycosyl donor, thereby successfully establishing O-linked Fmoc-protected threoninyl monosaccharide in an excellent yi

(Chemical Equation Presented) Aromatic aldehydes can be readily protected as acetals with 1,2- and 1,3-diols by using vanadyl triflate as a catalyst in CH3CN at ambient temperature. Carbohydrate-based 1,2- and 1,3-diols can similarly be protected in good to excellent yields. The catalyst can be readily recovered from the aqueous layer. In combination with vanadyl triflate-catalyzed sequential regioselective, reductive acetal opening and chemoselective acylations, the title method allows for differential functionalization of all four hydroxyl units in a given glucopyranoside.
