  Gold(III)-Catalyzed Glycosidations for 1,2-trans and 1,2-cis Furanosides

  摘要：

  Stereoselective synthesis of furanosides is still a daunting task, unlike the pyranosides, for which several methods exist. Herein, a unified stereoselective strategy for the synthesis of 1,2-trans and 1,2-cis furanosides is revealed for seven out of eight possible isomers of pentoses. The identified protocol gives access to diastereoselective synthesis of α- and β-araf, ribf, lyxf, and α-xylf furanosides. 1,2-trans glycosides were synthesized by the use of propargyl 1,2-orthoesters under gold-catalyzed glycosidation conditions, and subsequently, they are converted into 1,2-cis glycosides through oxidation-reduction as the key functional group transformation. All the reactions are found to be fully diastereoselective, mild, and high yielding.

  An Olefin Metathesis Route for the Preparation of (1→6)-Linked C-Disaccharide Glycals. A Convergent and Flexible Approach to C-Saccharide Synthesis

  摘要：

  A convergent route to a variety of C-1-disaccharide glycals based on the olefin metathesis reaction of enol ethers and alkenes is described. The DCC-mediated coupling reaction of a variety of pentose enitols (la-c) with a number of C-5- and C-6-monosaccharide carboxylic acids (2a-e) gave the corresponding esters 3a-1 in good yield. Methylenation of these compounds was followed by ring-closing metathesis, mediated by the Schrock molybdenum catalyst 8 in warm toluene, to provide the target C-disaccharide glycals 5a-1. The formed enol ether double bond in 5a was then transformed, via standard manipulations, into a variety of C-disaccharide derivatives 21-25.

  The 3,5-di-O-benzoyl n-pentenyl orthoesters of the four pentofuranoses have been prepared. The first key intermediate in each case is the methyl pentofuranoside(s), and a user-friendly procedure for the preparation of each, based on the Callam−Lowary precedent, is described, whereby formation of the crucial α/β anomeric mixture is optimized. The mixture is used directly to prepare the corresponding

  unrelated transporters showed similar but distinct patterns of inhibition, revealing differing selectivities for the different nucleosides and their analogues. Binding of nucleosides to NupG required the presence of hydroxyl groups at each of the C-3' and C-5' positions of ribose, while binding to NupC required only the C-3' hydroxyl substituent. The greater importance of the ribose moiety for binding to

  测试了一系列46种天然核苷和类似物（主要是基于腺苷的）作为从大肠杆菌中富集的，与H（+）连接的核苷转运蛋白NupC和NupG吸收[U-（14）C]尿苷的抑制剂。这两个在进化上不相关的转运蛋白显示出相似但不同的抑制模式，揭示了对不同核苷及其类似物的不同选择性。核苷与NupG的结合需要在核糖的C-3'和C-5'位置分别存在羟基，而与NupC的结合仅需要C-3'羟基取代基。核糖部分对于结合NupG的重要性更高，与该蛋白质和寡糖之间的进化关系一致：运输者的主要促进者超家族（MFS）的H（+）同向转运蛋白（OHS）亚家族。对于两种蛋白质，C-3'处的天然α-构型和C-1'处的天然β-构型对于配体结合都是必需的。发现腺苷的咪唑环中的N-7和C-6的氨基对于结合并不重要，并且两个转运蛋白都显示出C-6 / N取代的灵活性。N-1和N-3中的一个或两个对腺苷类似物与NupC的结合很重要，但对NupG的结合

  A new two step procedure for the synthesis of methyl 2,3-anhydro-α-d-lyxofuranoside and methyl 2,3-anhydro-β-d-ribofuranoside from d-xylose involving the intramolecular Mitsunobu reaction is presented. Likewise, methyl 2,3-anhydro-α-l-lyxofuranoside is obtained from l-arabinose. Cyclic sulfites with d-ribo configuration, synthetic equivalents of the corresponding anhydrosugars, are prepared in three steps from d-ribose.

  Abstract Benzyl methylene carbon resonances in perbenzylated methyl furanosides have been assigned by using a combination of INADEQUATE and 13 C- 1 H shift-correlation n.m.r. spectroscopies. We find that one-bond carbon-carbon coupling constants between furanosyl-ring carbon atoms and the shifts of benzyl methylene carbon resonances are related to the relative orientation of substituents on the furanosyl

  摘要通过结合INADEQUATE和13 C-1 H位移相关NMR光谱学，确定了苄基甲基呋喃糖苷中的苄基亚甲基碳共振。我们发现呋喃糖基环碳原子之间的单键碳-碳偶联常数和苄基亚甲基碳共振的位移与呋喃糖基环上取代基的相对取向有关。重新检查过苄基甲基吡喃糖苷的位移数据表明，相同的潜在现象类似地影响吡喃糖基环碳原子及其苄基亚甲基碳取代基的屏蔽。
