  Synthesis of neutral glycosphingolipids from Zygomycetes

  摘要：

  Novel neutral glycosphingolipids (NGSLs) containing Gal-alpha l -> 6Gal, previously found in the Zygomycetes species Mucor hiemalis, were synthesized. The structures of these compounds are different froth those of other fungal GSLs, and they are expected to be involved in host-parasite interactions. A key step in their synthesis is direct 1,2-cis alpha-selective galactosylation of 4,6-diol tri- and tetrasaccharide acceptors with a galactosyl donor in the presence of N-iodosuccinimide (NIS)/trifluoromethane-sulfonic acid (TfOH). The fully protected glycosides were deprotected to give the two target glycosphingolipids. (C) 2008 Elsevier Ltd. All rights reserved.
