Syntheses of linear tetra-, hexa-, and octa-saccharide fragments of the i-blood group active poly-(N-acetyl-lactosamine) series. Blockwise methods for the synthesis of repetitive oligosaccharide sequences.

N-Phthaloylation of lactosamine gave various glycosyl donors (beta-chloride, beta-trichloroacetimidate) and glycosyl acceptors (3',4'-diol). Coupling of the chloride with a methyl beta-D-glycoside led to the tetrasaccharide fragment, beta-D-Galp-(1----4)-

SYNTHESIS OF AN OCTASACCHARIDE FRAGMENT OF THE POLYLACTOSAMINE SERIES BY A BLOCKWISE APPROACH

Block synthesis of an octasaccharide, β-(1-3) linked tetramer of N-acetyllactosamine, is reported.Intermediate di- and tetrasaccharides were converted either into trichloroacetimidates acting as glycosyl donors or into vicinal diols acting as glycosyl acc

The synthesis of derivatives of lactosamine and cellobiosamine to serve as probes in studies of the combining site of the monoclonal anti-I Ma antibody

Syntheses are reported for a variety of structures used in a continuation of our studies of the combinig site of the monoclonal anti-I Ma antibody.These structures include that N-acetyl, N-formyl, and N-pivalyl derivatives of methyl-β-D-lactosaminide, the ethyl, propyl, isopropyl, and isobutyl β-glycosides of N-acetyllactosamine and the βDGal(1->4)βDGlcNAc(1->6)-, βDGal(1->4)βDGlcNH2(1->6)-, βDGal(1->4)βDGlcNCOCF3(1->6)-, and βDGlc(1->4)βDGlcNAc(1->6)-derivatives of 1,2;3,4-di-O-isopropylidene-α-D-galactopyranose.Also, preparations of 6-deoxy-βDGal(1->4)βDGlcNAc(1->6)α,βDGal and βDGlcNAc(1->6)βDGal(1->4)βDGlcNAcOCH3 are described.
