T. Takeda et al., TOTAL SYNTHESIS OF OCTASACCHARIDE RELATED TO GLYCOSPHINGOLIPID FROM THE SPERMATOZOA OF BIVALVES, Chemical and Pharmaceutical Bulletin, 41(11), 1993, pp. 2058-2060
Octasaccharide corresponding to the partial structure derived from lip
id IV has been prepared by coupling of the nonreducing end trisacchari
de with reducing end pentasaccharide as an acceptor in the presence of
dimethyl(methylthio)sulfonium triflate, followed by deprotection of a
desirable protected octasaccharide.
