  Diastereoselective syntheses of 1-deoxyhomonojirimycin and two new 1,5,6-trideoxy-1,5-iminoheptitols with d-allo- and l-talo-configuration

  摘要：

  The synthesis of 1-deoxyhomonojirimycin 2, as well as two new diastereomers, namely 1,5,6-trideoxy-1,5-imino-D-allo-heptitol 3 and 1,5,6-trideoxy-1,5-imino-L-talo-heptitol 4, is described. Compound 2 was obtained from 1,2:5,6-di-O-isopropylidene-alpha-D-glucofuranose-while 3 and 4 were obtained from 1, 2:5,6-di-O-isopropylidene-alpha-D-allofuranose. These compounds were transformed in a few steps to the corresponding beta-ketoesters 12 and 18, respectively, which were hydrogenated diastereoselectively in the presence of chiral ruthenium complexes with total control of the C-5 stereogenic centre. The resulting beta-hydroxyesters 13, 19a and 19b are key intermediates for the syntheses of the 1,5,6-trideoxy-1,5-iminoheptitols 2, 3 and 4, respectively. (c) 2006 Elsevier Ltd.

  method for the direct hydroxymethylation of aldehydes and ketones via pinacol cross-coupling with paraformaldehyde is described. The reaction is promoted by vanadium(II) ions which are conveniently generated from the reduction of VCl3(THF)3 with zinc dust. Excellent yields of terminal diols are obtained and stereoselective coupling is observed with some chiral aldehydes and ketones.

  Abstract A mild and efficient chemoselective method has been developed for the preparation of acetals and gem‐diacetates in good to excellent yields through a reaction of aldehydes with ethlyleneglycol or acetic anhydride using catalytic amounts of lanthanum(III) nitrate hexahydrate as a catalyst under solvent‐free conditions.

  synthetic tools to introduce saccharide derivatives into functionally complex molecules is of great interest, particularly in the field of drug discovery. Herein, we report a new route toward highly functionalized, arylated saccharides, which involves nickel‐catalyzed cross‐coupling of photoredox‐generated saccharyl radicals with a range of aryl‐ and heteroaryl bromides, triggered by an organic photocatalyst

  将糖衍生物引入功能复杂的分子中的合成工具的开发引起了极大的兴趣，特别是在药物发现领域。本文中，我们报告了一条通往高功能化，芳基化糖类的新途径，其中涉及由有机光催化剂引发的镍催化的光氧化还原产生的糖基与一系列芳基和杂芳基溴化物的交叉偶联。与现有方法相反，温和的反应条件实现了糖基序的芳基化，同时保留了异头碳，因此提供了一种至今仍未得到充分研究的芳基化糖苷。为了证明该策略在后期功能化中的潜力，合成了多种结合糖部分的结构复杂的分子。

  The prevalence of diabetes throughout the world continues to increase and has become a major health issue. Recently there have been several reports of inhibitors directed toward the sodium-dependent glucose cotransporter 2 (SGLT2) as a method of maintaining glucose homeostasis in diabetic patients. Herein we report the discovery of the novel O-xyloside 7c that inhibits SGLT2 in vitro and urinary glucose
