  Synthesis of C‐Glycosyl Phosphate and Phosphonate, Analogues of N‐Acetyl‐α‐d‐Glucosamine 1‐Phosphate

  摘要：

  Synthesis of alpha-C-ethylene phosphate and phosphonate as well as alpha-C-methylene phosphate analogues of N-acetyl-alpha-D-glucosamine I-phosphate is reported starting from the common perbenzylated 2-acetamido-2-deoxy-alpha-C-allyl glucoside. Anomerisation of the corresponding amino alpha-C-glucosyl aldehyde to the beta-aldehyde was observed. Thus, both amino alpha- and beta-C-glucosyl methanol were obtained after reduction.

• Synthesis of Novel Donor Mimetics of UDP-Gal, UDP-GlcNAc, and UDP-GalNAc as Potential Transferase Inhibitors

  日期：2000.1.1

  For the enzymatic transfer of galactose, N-acetylglucosamine, and N-acetylgalactosamine, UDP-Gal (1), UDP-GlcNAc (2), and UDP-GalNAc (3) are employed, and UDP serves as a feedback inhibitor. In this paper the synthesis of the novel UDP-sugar analogues 4, 5, and 6 as potential transferase inhibitors is described. Compounds 4-6 feature C-glycosidic hydroxymethylene linkages between the sugar and nucleoside

  Diethyl C-(2 -deoxy-2-acetamido- beta-D-mannopyranosyl)methylphosphonate and dimethyl C-(2-deoxy-2-acetamido-beta-D-glucopyranosyl)methylphosphonate were stereoselectively prepared from N-acetyl D-glucosamine. Routes to such compounds starting frorn D-GlcNAc have been problematic, but we have found short and efficient implementations of this highly desirable transformation. (C) 2003 Elsevier Ltd.

• C-Glycosidic UDP-GlcNAc Analogues as Inhibitors of UDP-GlcNAc 2-Epimerase

  日期：2004.8

  first step in the biosynthesis of neuraminic acid, the “epimerisation” of UDP-GlcNAc to ManNAc, is catalyzed by UDP-GlcNAc 2-epimerase. In this paper we report the synthesis of the C-glycosidic UDP-GlcNAc analogues 1−5 as substrate-based inhibitors of this enzyme. The focus is on the optimal distance and geometry of the connection between the sugar and the UDP-moiety, which are both important for recognition

  神经氨酸生物合成的第一步，即 UDP-GlcNAc 到 ManNAc 的“差向异构化”，是由 UDP-GlcNAc 2-差向异构酶催化的。在本文中，我们报告了 C-糖苷 UDP-GlcNAc 类似物 1-5 的合成，作为该酶的基于底物的抑制剂。重点是糖和 UDP 部分之间连接的最佳距离和几何形状，这对于 UDP-GlcNAc 2-差向异构酶的识别都很重要。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2004)
