  • Highly Diastereoselective α-Mannopyranosylation in the Absence of Participating Protecting Groups
    作者:David Crich、Weiling Cai、Zongmin Dai
    DOI:10.1021/jo9910482
    日期:2000.3.1
    6-di-O-benzyl-3,4-O-(2',3'-dimethoxybutane-2', 3'-diyl)-1-thia-alpha-D-mannopyranoside and its sulfoxide, following activation at -78 degrees C with benzenesulfenyl triflate or triflic anhydride, respectively, provide the corresponding alpha-mannosyl triflate as demonstrated by NMR spectroscopy. On addition of an acceptor alcohol alpha-mannosides are then formed. Similarly, S-phenyl 2,3-O-carbonyl-4, 6-O-benz

    DOI:10.1021/jo801414c
    日期:2008.9.19
    A fully stereocontrolled block synthesis of the title tetra- and hexasaccharides has been achieved taking advantage of the ability of the 4,6-O-benzylidene acetal to control the stereochemistry of the beta-D-glycero-D-mannoheptopyranoside unit and of a 2,3-O-diphenylmethylene acetal to install the alpha-L-rhamnopyranosidic linkages. Comparison of the spectral data for the hexasaccharide with that of the natural isolate confirms the structure of this very unusual and structurally challenging glycan.
  • An Efficient Synthesis of β-<i>C</i>-Glycosides Based on the Conformational Restriction Strategy:  Lewis Acid Promoted Silane Reduction of the Anomeric Position with Complete Stereoselectivity
    作者:Masaru Terauchi、Hiroshi Abe、Akira Matsuda、Satoshi Shuto
    DOI:10.1021/ol048525+
    日期:2004.10.1
    [reaction: see text] The reduction of glyconolactols having an anomeric carbon substituent by Et(3)SiH/TMSOTf proceeded with complete stereoselectivity to produce the corresponding beta-C-glycosides when the substrates were conformationally restricted in the (4)C(1)-chair form by a 3,4-O-cyclic diketal or a 4,6-O-benzylidene protecting group. Thus, the efficient construction of beta-C-glycosides was
