Efficient sialylations using N-glycolylneuraminic acid (Neu5Gc) phosphite donors having an acetyl or benzyl group on the glycolyl moiety are described in the synthesis of Neu5Gc-containing glycans. Both phosphite donors 1 and 2 were readily coupled with primary and secondary acceptor alcohols in propionitrile at -78 degrees C to provide the desired glycosides with good alpha-selectivities.
