Efficient sialylation with phosphite as leaving group

The search for an acid labile leaving group attached to the anomeric position of O-protected N-acetylneuraminic acid led to phosphite derivative 1c which provided in the presence of catalytic amounts of trimethylsilyl trifluoromethanesulfonate the desired
