  • Synthesis of sulfated glucuronyl glycosphingolipids; carbohydrate epitopes of neural cell-adhesion molecules
    作者:Takahisa Nakano、Yukishige Ito、Tomoya Ogawa

    日期:1993.4
    glycosphingolipids isolated from the human peripheral nervous system, HO3S-3-beta-GlcpA-(1-->3)-[beta-D-Galp-(1-->4)-beta-D-GlcpNA c-(1-->3)]n- beta-D-Galp-(1-->4)-beta-D-Glcp-(1-->1)-Cer (n = 1, 2) (1 and 2) were synthesized. The glycan part of target molecules was designed to be constructed from glucuronate, lactosamine, and lactose fragments 8, 9 (or 10), and 11, which in turn were synthesized stereo- and/or

    日期:1998.5.1
    A total synthesis of tumor-associated glycolipid antigen sialyl Lea, and a first total synthesis of glycononaosyl ceramide with a dimeric Lea sequence are described. Regio-and stereoselective coupling of sialyl donor 12 with suitably protected Lea trisaccharide fluoride 17 was performed by orthogonal glycosylation to give the expected tetrasaccharide 18 in good yield.

    tert-Butyldimethylsilyl 2-azido-4,6-benzylidene-glucopyranoside 3 proved to be a versatile starting material for the synthesis of Lex trisaccharide building block 7. Transformation into glycosyl donor 8a and acceptor 9, respectively, led to all building blocks required for the extension to hexa-, nona-, and dodecasaccharides 8b–d; with lactose acceptor 13 the corresponding octa-, undeca-, and tetradecasaccharides
