Synthesis of trisaccharide 6' SiaLec and its 6-O-Su derivative

The synthetic approach to 6'SiaLec and its 6-O-Su derivative comprised α-sialylation of a protected Lec derivative, 2,3-di-OAcGalβ1-3(3-OAc-6-OBn)GlcNAcβ1-Osp (68% yield) as the key stage. Deprotection of the obtained trisaccharide (three stages, 79% overall yield) led to Neu5Acα2-6Galβ1-3GlcNAcβ1-Osp; partial deprotection followed by selective sulfation and total deprotection - to Neu5Acα2-6Galβ1-3(6-O-Su)GlcNAcβ1-Osp (four stages, 72% overall yield).

ARTIFICIAL ANTIGENS AND AFFINITY SORBENTS WITH GROUPS SPECIFICITIES Lea. Leb, and Led

Oligosaccharides of the Lewis system have been synthesized in the form of 3-aminopropylglycosides, from which neoglycoproteins and affinity sorbents have been obtained.All three oligosaccharides were obtained from one and the same precursor.
