Oligosaccharides from "Standardized Intermediates". Synthesis of a Branched Tetrasaccharide Glycoside Related to the Blood Group B Determinant

Article abstract of DOI:10.1021/ja00389a061

A branched tetrasaccharide glycoside (16) isomeric with the human blood group B determinant (type 1) was synthesized from "building block" derivatives of the component monosaccharides.Initially a 2-O-benzoyl-3,6-di-O-benzyl-4-O-substituted-α-D-galactopyra
