  Efficient Syntheses of a Series of Glycosphingolipids with 1,2‐trans‐Glycosidic Linkages

  摘要：

  A series of glycosphingolipids with 1,2-trans-glycosidic linkages were synthesized in the presence of neighboring group participation using trichloroacetimidates as glycosyl donors and an azido-sphingosine as the glycosyl acceptor. During the preparation of the target compounds, it was found that the alpha-L-arabinopyranosyl unit in target 7e and intermediates 7b - 7d existed in the C-1(4) conformation and that the b-L-fucopyranosyl unit in 10e adopted the C-4(1) conformation.
