Orthogonal glycosylation strategy in synthesis of extended blood group B determinant

Article abstract of DOI:10.1016/0040-4039(96)00901-X

The orthogonal glycosylation strategy was applied for the synthesis of extended blood type B determinant (2) of a novel glycolipid 1. Key features in the synthesis are 1) four monosaccharide units were synthesized as either glycosyl fluoride or thioglycoside to be engaged to the orthogonal glycosylation strategy and 2) all necessary manipulations were completed at the monosaccharide level, therefore, manipulations during the elongation of sugar chain were minimized.
