  One-pot synthesis of β-d-Gal>(1 → 4)[β-d-Galp(1 → 6)]-d-GlcNAc, a ‘core’ trisaccharide linked O-glycosidically in glycoproteins of Trypanosoma cruzi

  摘要：

  Tin(IV) chloride-promoted condensation of benzyl 2-acetamido-3-O-benzoyl-2-deoxy-alpha-D-glucopyranoside (4) with penta-O-benzoyl-beta-D-galactopyranose (6) gave the derivative of beta-D-Galp-(1 --> 6)-alpha-D-GlcNAc 7 in 80% yield, This was glycosylated with penta-O-benzoyl-alpha,beta- D-galactofuranose (5>, employing the same catalyst, to afford the protected benzyl per-O-benzoyl-beta-D-Galf(1 --> 4)[beta-D-Galp(1 --> 6)]D-GlcNAc 10 in 41% yield, Alternatively, compound 10 was obtained directly in a one-pot reaction from 4, by sequential addition of 6 and 5 (34% yield). beta-Glycosidic linkages were diastereoselectively formed. De-O-benzoylation of 10, followed by heterogeneous catalytic transfer hydrogenolysis of the benzyl group afforded the free trisaccharide beta-D-Galf(1 --> 4)[beta-D-Galp(1 --> 6)]-D-GlcNAc (14) in 98% yield from 10. Sodium borohydride reduction of 14 gave the corresponding alditol, whose spectral data were identical to those reported for the alditol obtained from the 38-43 kDa cell-surface glycoprotein of Trypanosoma cruzi.

  Various partly protected sugars (gluco-, manno-, and galactopyranosides) were acetalized with methyl pyruvate in moderate to good yield with BF3-etherate as the condensing reagent. Thus, (1-methoxycarbonyl)ethylidene glycosides were obtained diastereoselectivity.

  各种部分受保护的糖（葡萄糖基，甘露糖苷和半乳糖吡喃糖苷）以丙酮酸甲酯缩醛化，并以BF 3-醚酸酯为缩合试剂。因此，获得了（1-甲氧基羰基）亚乙基糖苷的非对映选择性。

  In a continuation of our studies on the characterization of the glycoproteins of T. cruzi new galactofuranosyl disaccharides were synthesized. beta-D-Galf-(1-3)-D-GlcNAc (1) was prepared by employing the trichloroacetamidate procedure for the glycosylation step, The mild conditions of this reaction are appropriate for condensation of 2,3,5,6-tetra-O-benzoyl-beta-D-galactofuranosyl trichloroacetamidate (6) with acid-labile benzyl 2-acetamido-4,6-O-benzylidene-2-deoxy-alpha-D-glucopyranoside (3). On the other hand, tin(IV) chloride promoted condensation of benzyl 2-acetamido-3-O-benzoyl-2-deoxy-alpha-D-glucopyranoside (11) with penta-O-benzoyl-alpha,beta-D-galactofuranose (4) gave the derivative of beta-D-Galf-(1-6)-D-GlcNAc (2) in 78% yield.
