  摘要：

  C-6开环反应：利用从辛-1-炔或苯乙炔生成的炔基负离子，打开甘露呋喃糖苷1的5,6-环硫酸酯衍生物，分别得到相应的6-炔基-6-脱氧衍生物2和3。5,6-环硫酸酯1与源自单糖的锂炔化物反应，形成伪C-二糖5。通过在THF/HMPA中使用锂炔化物的一锅法程序，制备了对称伪C-二糖7。该方法应用于葡萄呋喃糖11的5,6-环硫酸酯衍生物，与源自甘露呋喃糖9的炔化负离子反应，得到相应的非对称伪C-二糖13。

  日期：2007.8

  C-6 opening of 5,6-cyclic sulfate derivatives of mannofuranose with a thiolate anion followed by acidic hydrolysis of the acyclic sulfate gave 6-S-alkyl derivatives in good yields (70-95%) and short reaction times (10-15 min). This methodology was applied to the synthesis of methyl 2,3-O-isopropylidene-6-S-(2,3,4,6-tetra-O-acetyl-beta-D-glucopyranosyl)-6-thio-alpha-D-mannofuranoside (70%), 2,3-O-isopropylidene-6-S-(2,3,4,6-tetra-O-acetyl-beta-D-glucopyranosyl)-6-thio-alpha-D-mannofuranose (87%) and 2,3-O-isopropylidene-6-S-(1,2:3,4-di-O-isopropylidene-alpha-D-galactopyranos-6-yl)-6-thio-alpha-D-mannofuranose (87%). @ 2007 Elsevier Ltd.

  Methyl 6-C-alkyl-6-deoxy-alpha-D-mannofuranoside derivatives have been synthesized from methyl 2,3-O-isopropylidene-5,6-O-sulfuryl-alpha-D-mannofuranoside (1). In a Path A, reaction of the 5,6-cyclic sulfate 1 with 2-lithio-1,3-dithiane afforded 2-(methyl 6-deoxy-2,3-O-isopropylidene-alpha-D-mannofuranosid-6-yl)-1,3-dithiane (2). Treatment of 2 with n-butyllithium then alkyl iodide gave the corresponding 2-(methyl 5-O-alkyl-6-deoxy-2,3-O-isopropylidene-alpha-D-mannofuranosid-6-yl)-1,3-dithiane. Reaction of 2 with n-butyllithium and 5,6-cyclic sulfate 1 furnished 2-[methyl 6-deoxy-2,3-O-isopropylidene-5-O-(methyl 6-deoxy-2,3-O-isopropylidene-alpha-D-manno-furanosid-6-yl)-alpha-D-mannofuranosid-6-yl]-1,3-dithiane. 2-(Methyl 6-deoxy-2,3-O-isopropylidene-5-O-methyl-alpha-D-mannofuranosid-6-yl)-1,3-dithiane was converted into the lithiated anion, which after treatment with alkyl halide afforded the corresponding 2-alkyl-C-(methyl 6-deoxy-2,3-O-isopropylidene-5-O-methyl-alpha-D-mannofuranosid-6-yl)-1,3-dithiane. In a Path B, 5,6-cyclic sulfate 1 reacted with 2-alkyl-2-lithio-1,3-dithiane derivatives, which led after acidic hydrolysis to 2-alkyl-2-(methyl 6-deoxy-2,3-O-isopropylidene-alpha-D-mannofuranosid-6-yl)-1,3-dithiane accompanied by methyl 6-deoxy-2,3-O-isopropylidene-alpha-D-lyxo-hexofuranos-5-uloside as the by-product. This methodology was applied to synthesize 2-(methyl 6-deoxy-2,3-O-isopropylidene-5-O-methyl-alpha-D-mannofuranosid-6-yl)-2-(methyl 6-deoxy-2,3-O-isopropylidene-alpha-D-mannofuranosid-6-yl)-1,3-dithiane.

  C-6 ring opening of 5,6-cyclic sulfate derivatives of protected manno and glucofuranose with carbohydrate alkoxides gave ether linked pseudo-di or trisaccharides. Use of methyl 2,3-O-isopropylidene-5,6-O-sulfuryl-alpha-D-mannofuranoside 1 led to protected pseudo-disaccharide D-Glcf-(3-->6)-D-Manf-(5-->6)-D-Manf 4 and protected pseudo-trisaccharide D-Manf-(6-->3)-D-Glcf-(6-->3)-D-Glcf 11 derivatives in 66% and 41% overall yields, respectively.
