Abstract

Building Units of Oligosaccharides. Part 104. Synthesis of Branched Tetrasaccharide and Pentasaccharide Structures of N-Glycoproteins Methylated at 4'-OH of the Branching Unit. -The tetrasaccharide (Ia) and the pentasaccharide (Ib) are synthesized by adding the respective functionalized building blocks. The compounds are useful for studies of the substrate specificities of N-glucosaminyltransferases I and II in the biosynthesis of N-linked oligosaccharides. -(PAULSEN, H.; WILKENS, R.; RECK, F.; BROCKHAUSEN, I.; Liebigs Ann.
