An efficient and direct one-pot glycosylation method using anomeric hydroxy sugars as glycosyldonors, employing 3-fluorophthalic anhydride and triflic anhydride as activating agents, has been developed. The present glycosylation utilizing 3-fluorophthalic anhydride resulted in few to no undesired self-condensed esters than the glycosylationusing phthalic anhydride. Intermediates in the present glycosylation
