We have succeeded in achieving a facile access to 4-nitrophenyl and 4-methylumbelliferyl-α-sialosides. To sialosyl chlorides which are fully protected with acetyl groups as glycosyl donors, the action of phenols with diisopropylethylamine in acetonitrile brought about high yield as well as facile product isolation.
