[GRAPHICS]The installation of the novel N,N-dimethylglycolamide ester auxiliary onto the C(1)-position of protected neuraminic acid donors allows for the exploitation of C(1)-neighboring group participation to generate sialoside conjugates with good to excellent or-selectivity under a variety of sialylation protocols, including those that would otherwise lead to nonselective or beta -selective sialoside products.
