    摘要:
    已经开发了炔烃与 2-苄基丙二酸二甲酯的电化学脱芳构化螺环化反应制备螺[4.5]十-三烯酮。该方法采用二茂铁(Cp 2 Fe)作为电催化剂,从C-H基丙二酸盐制备碳中心自由基中间体,避免了贵金属试剂、牺牲化学氧化剂和2-溴丙二酸盐的消耗。在温和条件下可有效制备多种螺环化合物,并获得满意的结果。

    Mechanistic and stereochemical study of phenylpyruvate tautomerase
    摘要:
    A variety of substrates and potential enol/enolate mimics for the product/transition state of the enzyme phenylpyruvate tautomerase (E.C. 5.3.2.1) have been prepared and studied. Their stereostructures have been secured by a combination of NMR spectroscopy based on vicinal H-F and H-C coupling constants and X-ray crystallography. On the basis of the inhibition by stereoisomeric substituted cinnamates, it has been concluded that the enzyme produces the thermodynamically less stable (E) enol via a syn tautomerization transition state. Free energy profiles for the reaction suggest that vinyl fluorides act as product analogues. Because amide and dicarboxylate enolate mimics are relatively poor inhibitors of the enzyme, it is believed that an enolate is not involved in the tautomerization process.

  • Novel Method for Synthesizing Spiro[4.5]cyclohexadienones through a Pd-Catalyzed Intramolecular <i>ipso</i>-Friedel−Crafts Allylic Alkylation of Phenols

    The first successful Pd-catalyzed intramolecular ipso-Friedel−Crafts allylic alkylation of phenols, which provided a new access to spiro[4.5]cyclohexadienones, is described. The present method could be applied to catalytic enantioselective construction of an all-carbon quaternary spirocenter.

  • Amides as surrogates of aldehydes for C-C bond formation: amide-based direct Knoevenagel-type condensation reaction and related reactions
    作者:Wei Ou、Pei-Qiang Huang
    DOI:10.1007/s11426-019-9586-3
    日期:2020.1
    Aldehydes are perhaps the most versatile compounds that enable many C-C bond forming reactions, which are not amenable for other subclasses of carbonyl compounds. We report the first use of amides as surrogates of aldehydes for C-C bond formation, namely, the direct Knoevenagel-type condensation based on amides. The one-pot method consists of controlled reduction of an amide with LDBIPA [LiAlH(iBu)2(OiPr)]
    醛也许是最能实现许多CC键形成反应的多功能化合物,这些不适用于羰基化合物的其他亚类。我们报道了酰胺的首次使用作为CC代形成醛的替代品,即基于酰胺的直接Knoevenagel型缩合反应。一锅法包括用LDBIPA [LiAlH(i Bu)2(O i Pr)]控制酰胺还原,路易斯酸介导的反应性亚胺离子中间体的释放,亲核加成和原位反应消除胺。该反应显示出良好的官能团耐受性。我们还证明了Schwartz试剂可以用作LDBIPA的替代品。使用硝基甲烷和甲硅烷基烯醇醚作为亲核试剂分别为空前的基于酰胺的硝基-羟醛缩合反应和羟醛缩合反应开辟了道路。
