  Preferred conformation of C-glycosides. 10. Synthesis and conformational analysis of carbon trisaccharides

  摘要：

  A flexible and efficient synthesis of the carbon trisaccharide 2 related to the Type II O(H) blood group determinant has been developed. This route was applied to the synthesis of the trisaccharides 3, 4, and 5. The preferred solution conformations of compounds 2-5 were determined on the basis of vicinal coupling constants in the H-1 NMR spectrum. Each of the four trisaccharides adopts a distinct and well-defined solution conformation in accord with the predictions made on the basis of the preference of the C-glycosidic bond for the ''exo-anomeric'' conformation and the analysis of 1,3-diaxial-like interactions around the C-aglyconic bond.

  A stereoselective two-carbon homologation protocol has been developed and applied to the asymmetric synthesis of the hexose monosaccharides D-galactose, D-fucose, D-idose, D-6-deoxyidose, D-talose and D-6-deoxytalose.

  我们开发了一种立体选择性双碳同源化方案，并将其应用于 D-半乳糖、D-岩藻糖、D-idose、D-6-脱氧idose、D-塔罗糖和 D-6-deoxytalose 六糖单糖的不对称合成。

  The syntheses of C-trisaccharides 1-4, carbon analogs of the human blood group determinant II-type II, have been achieved in a flexible and efficient manner. Vicinal coupling constants in the H-1 NMR spectrum provide experimental evidence that each of the four compounds 1-4 possesses a unique solution conformation, in accord with the predictions made on the basis of the preference of the C-glycosidic bond for the ''exo-anomeric'' conformation and the influence of 1,3-diaxial like interactions about the C-aglyconic bond.
