  描述：

  phenyl 2-O-benzoyl-3,4-di-O-benzyl-1-thio-β-D-glucopyranoside 在 sodium tetrahydroborate 作用下， 以 N,N-二甲基甲酰胺 为溶剂， 反应 8.0h， 生成 phenyl 2-O-benzoyl-3,4-di-O-benzyl-6-deoxy-1-thio-β-D-glucopyranoside

  Preparation and diastereomeric separation of an (S)- and (R)-1-(methoxycarbonyl)tridec-10-yl glucoside derivative, a precursor for a monosaccharide constituent of resin glycosides

  摘要：

  The 6-O-mesyl derivative of phenyl 1-thio-beta-D-glucopyranoside was prepared from D-glucose as a synthetic equivalent of a 6-deoxy-hexosyl donor. Racemic methyl 11-hydroxytetradecanoate (methyl convolvulinolate) was synthesized by Grignard reaction of propylmagnesium bromide with 10-undecenal followed by hydroboration. Both intermediates were coupled by NIS-TfOH-promoted glycosidation to give a mixture of two diasteromeric glucopyranosides, which were separated on a preparative scale by medium pressure chromatography. One of the products was identified as having the natural (S)-configuration by comparison of its H-1 NMR spectrum with an authentic sample prepared from the corresponding chiral hydroxyfatty acid.

  Glycosidation of silicon-connected glycosyl donors on polystyrene resin is described. Thiophenyl glycoside 2a and glucopyranosyl fluoride 2 b reacted with glycosyl acceptor 3 (R2 = Bn) to give disaccharide 4a in 96% and 70% yields, respectively. Glycosidation of thiophenyl glucoside 2 a (R1 = Bn or Bz) with glycosyl acceptor 3 (R2 = Bn or Ac) yielded 4a–4c in satisfactory yields and 4d in moderate
