Synthesis and NMR study of a heptasaccharide, epitope of the stage-specific embryonic antigen-1 (SSEA-1).

This paper describes an efficient synthesis of the beta-2-trimethylsilylethyl glycoside of lacto-N-fucoheptaose based on a highly stereo- and regioselective glycosylation between a Lewis(x) trisaccharidic donor and a tetraol tetrasaccharidic acceptor. The title compound was characterized by high-resolution NMR spectroscopy.
