Imidazolium cation supported solution-phase assembly of homolinear alpha(1-->6)-linked octamannoside: an efficient alternate approach for oligosaccharide synthesis

An efficient, simple convergent assembly of a homolinear alpha(1-->6)-linked octamannosyl thioglycoside was obtained starting from imidazolium cation-tagged mannosyl fluoride and thiomannoside using block couplings. During chain elongation glycosylation reactions no column chromatographic purifications were used.
