Abstract

A very efficient strategy for the chemical synthesis of the sialyl Lewis X tetrasaccharide is reported. Starting from four simple monosaccharide building blocks, sialyl Lewis X was obtained in seven steps. By using similar strategy, sialyl LacNAc and sulfated sialyl LacNAc trisaccharides were also synthesized.
