Abstract

Efficient and systematic syntheses of four neutral glycosphingolipids that have been isolated from the metacestodes of Echinococcus multilocularis have been achieved. A key step is the direct glycosylation of galactosyl donors using thioglycosides with benzoyl ceramide in the presence of N-iodosuccinimide (NIS)/TfOH, which gave the desired oligosaccharide derivatives. The fully protected glycosides 13, 20, 22 and 25 were deprotected to give four target glycosphingolipids (1-4).
