  Structure−Activity Relationships of N-Hydroxyurea 5-Lipoxygenase Inhibitors

  摘要：

  The discovery of second generation N-hydroxyurea 5-lipoxygenase inhibitors was accomplished through the development of a broad structure-activity relationship (SAR) study. This study identified requirements for improving potency and also extending duration by limiting metabolism. Potency could be maintained by the incorporation of heterocyclic templates substituted with selected lipophilic substituents. Duration of inhibition after oral administration was optimized by identification of structural features in the proximity of the N-hydroxyurea which correlated to low in vitro glucuronidation rates. Furthermore, the rate of in vitro glucuronidation was shown to be stereoselective for certain analogs. (R)-N-[3-[5-(4-Fluorophenoxy)-2-furyl]-1-methyl-2-propynyl]-N-hy- droxyurea (17c) was identified and selected for clinical development.

  有机硼酸与N-烷基羟胺的无金属和无碱室温胺化

  摘要：

  我们发现，现成的N烷基羟胺是在三氯乙腈存在下胺化有机硼酸的有效试剂。该胺化反应在室温下快速进行，在不添加金属或碱的情况下，它可以耐受各种官能团，可用于两个复杂单元的后期组装。

• Regioselective Asymmetric Formal (3+2) Cycloadditions of Nitrone Ylides from Isatins and Enals
  作者：Yu-Rong Chen、Gu Zhan、Wei Du、Ying-Chun Chen

  日期：2016.12.7

  A highly regio‐, diastereo‐ and enantioselective formal (3+2) cycloaddition reaction of nitrone ylides from isatins and α,β‐unsaturated aldehydes was developed via iminium catalysis in the presence of an additional base, furnishing a spectrum of 1′‐hydroxy‐3,2′‐pyrrolidinylspirooxindole frameworks. Interestingly, the regioselectivity could be finely switched in the reactions between nitrone ylides and

• Metal- and Base-Free Room-Temperature Amination of Organoboronic Acids with <i>N</i> -Alkyl Hydroxylamines

  N‐alkyl hydroxylamines are effective reagents for the amination of organoboronic acids in the presence of trichloroacetonitrile. This amination reaction proceeds rapidly at room temperature and in the absence of added metal or base, it tolerates a remarkable range of functional groups, and it can be used in the late‐stage assembly of two complex units.
