Synthetic Studies on Sialoglycoconjugates 12: Total Synthesis of Sialyl Neolactotetraosyl Ceramide

Abstract
Sialoglycoconjugates such as glycoproteins and glycolipids are present as components of cell memberanes and play important roles1,2 in biological systems. Sialyl neolactotetrasyl ceramide (IV3NeuAcnLc4Cer), a complex type of ganglioside, was isolated as the major ganglioside of human erythrocytes3 and was shown to be a receptor of that this glycolipid induces granulocytic differentiation of human premyelocytic leukemia cell.
