  • Synthesis of Novel Donor Mimetics of UDP-Gal, UDP-GlcNAc, and UDP-GalNAc as Potential Transferase Inhibitors
    作者:Andreas Schäfer、Joachim Thiem
    DOI:10.1021/jo990766l
    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

  • Ring-Opening of Aziridine-2-Carboxamides with Carbohydrate C1-<i>O</i>-Nucleophiles. Stereoselective Preparation of α- and β-<i>O</i>-Glycosyl Serine Conjugates
    作者:Daniel A. Ryan、David Y. Gin
    DOI:10.1021/ja804589j
    日期:2008.11.19
    The stereoselective formation of the alpha-GalNAc-Ser linkage via the ring opening of aziridine-2-carboxamides with pyranose C1-O-nucleophiles is described. The process is tolerant to the native C2-NHAc group, can be modulated to provide either the alpha- or beta-glycoside through judicious choice of solvent and metal counterion, and is amenable to other classes of O-glycosyl-Ser constructs such as the B-GlcNAc-Ser and alpha-Man-Ser linkages. This coupling reaction also led to the development of the o-allylbenzyl (ABn) moiety as a new C-terminus carboxyl protective group, which allows for the use of novel methods for N- and C-terminus extension of amino acids following carbohydrate conjugation.
  • Convenient Preparation of Perbenzylated 2-Azido and 2-<i>N</i>-Acetylamino-2-Deoxy-<scp>d</scp>-Hexono-1,5-Lactones by Oxidation of the Corresponding Lactols

    2-Azido-3,4,6-tri-O-benzyl-2-deoxy-D-galacto, gluco and mannopyranoses (1, 2, 3) were oxidized with DMSO in the presence of acetic anhydride. From 1 and 2 the corresponding lactone derivatives were obtained in good yield (89-92%), whereas from 3, glucono-1,5-lactone was obtained (92%) after complete epimerization at C-2. 2-N-Acetylamino-3,4,6-tri-O-benzyl-2-deoxy-D-galacto, gluco and mannopyranoses (7, 8, 9) were obtained from the corresponding 2-azido phenylselenoglycopyranosides (13, 14, 15) by reduction, N-acetylation and hydrolysis catalyzed by mercury trifluoroacetate. Oxidation of 7 and 8 by tetra-n-propylammonium tetra-oxoruthenate (VII) in the presence of 4-methylmorpholine-N-oxide afforded the corresponding lactones in good yield (90%) and high purity. Epimerization at C-2 occurred during oxidation of 9 and perbenzylated D-glucono-1,5-lactone (11) was obtained (90%).
  • Stereocontrolled Synthesis of α-<i>C</i>-Galactosamine Derivatives via Chelation-Controlled <i>C</i>-Glycosylation

    or aldehydes under Barbier conditions led unexpectedly to the stereoselective synthesis of alpha-C-galactosamine derivatives in good yields. With carbonyl substrates, alpha:beta selectivities ranged from 20:1 to 5:1, and with aldehydes a stereoselectivity of approximately 5:1 was observed at C7 in favor of the S-isomer. The stereochemical preference of these C-glycosylation reactions is explained by
    在巴比尔条件下,二碘化sa通过酮或醛促进的二碘化mar还原的2-脱氧-2-乙酰氨基七乳糖基吡啶基砜α-5出乎意料地以高收率立体合成了α-C-半乳糖胺衍生物。对于羰基底物,α:β选择性范围为20:1至5:1,对于醛,在C7处观察到约5:1的立体选择性,有利于S-异构体。这些C-糖基化反应的立体化学偏好是通过α-定向异头糖基sa(III)化合物的中间体来解释的,该化合物通过金属离子与C2-乙酰氨基的螯合来稳定。
