Conversion of the carboxy group of sialic acid donors to a protected hydroxymethyl group yields an efficient reagent for the synthesis of the unnatural beta-linkage

New sialyl donors with a protected hydroxymethyl group at the anomeric center are over 1000 times more reactive than the normal ester containing sialylation reagent and give excellent yield (> 90%) with unusually high β-stereoselectivity in sialylation.
