A novel neo-glycolipid containing sialyl Lewis X determinant carried on the mucin GlcNAc beta 1-6GalNAc alpha core structure has been designed and synthesized. By employing this compound as a probe, the structure required for the recognition of anti-cancer antibodies, NCC-ST-439, has been elucidated. (c) 2005 Elsevier Ltd. All rights reserved.

transformation to the glycosylacceptor, was successfully coupled with the phenylthioglycoside of glucosamine (13) to give the core 6 structure (14). Following proper manipulation of the protecting groups for the hydroxyl, as well as the amino function, the resulting free hydroxyl of the tetrasaccharide at C3 of the GlcNAc was then fucosylated to give the desired pentasaccharide (19). This pentasaccharide
