    名称:
    The synthesis and biological evaluation of 1-C-alkyl-l-arabinoiminofuranoses, a novel class of α-glucosidase inhibitors
    摘要:
    The asymmetric synthesis of 1-C-alkyl-L-arabinoiminofuranoses 1 was achieved by asymmetric allylic alkylation (AAA), ring closing metathesis (RCM), and Negishi cross coupling as key reactions. Some of the prepared compounds showed potent inhibitory activities towards intestinal maltase, with IC50 values comparable to those of commercial drugs such as acarbose, voglibose, and miglitol, which are used in the treatment of type 2 diabetes. Among them, the inhibitory activity (IC50 = 0.032 mu M) towards intestinal sucrase of 1c was quite strong compared to the above commercial drugs. (C) 2010 Elsevier Ltd. All rights reserved.

    与羰基官能团相容的烷基锌试剂的简单制备
    摘要:
    在此,我们报道了一种在温和条件下使用钴催化从官能化烷基溴制备烷基锌化合物的直接方法。该过程仅需要由 CoBr 2组成的简单催化系统和联吡啶作为乙腈/吡啶混合物中的配体。该反应在空气和潮湿条件下稳定,为可行的程序开辟了道路。伯烷基溴和仲烷基溴上的各种官能团(例如酯、氰基和卤素)具有良好的耐受性,并能产生高产率的相应烷基锌化合物。此外,我们还成功地形成了带有酮和醛等敏感官能团的烷基锌试剂,且收率良好。这些烷基锌衍生物在钯催化的根岸与各种官能化芳基溴的交叉偶联中的直接应用证明了该方法的效率和稳健性。

    An efficient catalytic protocol for the three‐component assembly of benzyl bromides, carbon monoxide, and alkyl zinc reagents to give benzyl alkyl ketones is described, and represents the first nickelcatalyzed carbonylative coupling of two sp3‐carbon fragments. The method, which relies on the application of nickel complexed with an NN2‐type pincer ligand and a controlled release of CO gas from a solid

    secondary benzylic alcohols via tandem Ni-catalyzed cross-coupling reactions of aromatic 2-pyridyl esters with alkyl zinc reagents and carbonyl group reduction by Ni–H species is achieved. Preliminary mechanistic studies reveal that the Ni–H species is generated in situ via β-hydride elimination of the Negishi reagents. The reaction is catalyzed by bench-stable nickel salts under mild conditions with

  • Differentiating CBr and CCl Bond Activation by Using Solvent Polarity: Applications to Orthogonal Alkyl-Alkyl Negishi Reactions
    作者:Niloufar Hadei、George T. Achonduh、Cory Valente、Christopher J. O'Brien、Michael G. Organ

    日期:2011.4.18
    A pot to share: A CalkylCl bond can be rendered “dormant” or “active” in the Negishi alkyl–alkyl cross‐coupling by a simple solvent polarity “switch” (see scheme). Adjustment from a 1:2 to a 2:1 solvent ratio of dimethylimidazolidinone:tetrahydrofuran enables orthogonal alkyl–alkyl Negishi cross‐coupling strategies to be carried out on bifunctional bromochloroalkanes in one pot at room temperature
    一个共享的锅:通过简单的溶剂极性“转换”,在Negishi烷基-烷基交叉偶联中,AC烷基Cl键可被“休眠”或“激活”。将二甲基咪唑啉酮:四氢呋喃的溶剂比例从1:2调整为2:1,可以在室温下在一锅中对双官能烷烃进行正交烷基-烷基Negishi交叉偶联策略。
