| Abstract: | In order to elucidate the molecular specificity of the antimelanoma response induce by GM3 included in proteoliposome preparation, we designed syntheses of a series of neoglycolipids containing the trisaccharide portion of GM3 or its fragment. In the present paper, we synthesized two neoglicolipids containing as a lipid, a racemic glycerol unit substituted by two aliphatic octadecyl ether chains. The di‐ and trisaccharide derivatives were prepared as glycosides of the spacer by a sequence of isopropilidenation‐benzylation‐hydrolysis followed by sialylation. The condensation between the oligosaccharides and the lipid was performed by an amidation reaction. |
