  • Building blocks for glycopeptide synthesis: glycosylation of 3-mercaptopropionic acid and Fmoc amino acids with unprotected carboxyl groups
    作者:Mikael Elofsson、Björn Walse、Jan Kihlberg
    DOI:10.1016/0040-4039(91)80548-k
    日期:1991.12
    3-Mercaptopropionic acid and Fmoc amino acids, having unprotected carboxyl groups, were glycosylated with sugar 1,2-trans-acetates in 90 and 53–65% yields, respectively, under Lewis acid promotion. The synthesis of a neoglycopeptide illustrates the use of the building blocks in solid phase peptide synthesis.
    路易斯酸的促进下,将具有未保护羧基的3-巯基丙酸和Fmoc氨基酸分别与糖1,2-反式乙酸酯进行糖基化处理,产率分别为90%和53-65%。新糖肽的合成说明了结构单元在固相肽合成中的用途。
  • 3-bromo-2-bromomethylpropyl glycosides in the preparation of double-chain bis-sulfide neo-glycolipids

    日期:1987.4
    Abstract Boron trifluoride etherate-induced glycosidation of 3-bromo-2-bromomethylpropan-1-ol with sugar acetates gave the title glycosides of the following sugars of the d series: Glc p , Gal p , Glc p A, GlcNPhth p , Xyl p , β-Gal p -(1→4)-Glc p , and α-Gal p -(1→4)-Gal p . Treatment of the fully acetylated glycosides with alkanethiols and cesium carbonate in N,N -dimethylformamide followed by deacetylation

    unprotected carboxyl groups, were stereospecifically glycosylated in 62-82% yields, using saccharide 1,2-trans peracetates and Lewis acid catalysis. The resulting glycosylated building blocks were used in the synthesis of derivatives of helper-T-cell stimulating peptides, with the carbohydrate moiety located at the amino terminus, or internally in the peptide chain. 1H NMR spectroscopy in Me2SO-d6 showed
