    可切换的[3 + 2]和[4 + 2]伯丙烯基丙胺与异腈杂环化成咪唑和1,6-二氢嘧啶:催化剂负载可实现反应发散
    摘要:
    异腈1由于具有类似卡宾的反应性,因此通常在多种有机转化中用作单碳合成子。我们在本文中报道,异氰基还可以充当极化的三键,作为双原子合成子,与伯炔丙基胺进行杂环化15。此外,我们偶然发现,可以通过简单地改变催化剂负载量来调节反应路径。在0.1当量的Yb(OTf)3或TfOH的存在下,在1至15之间的反应通过正式的[3 + 2]环加成反应仅得到咪唑16。在较高的催化剂负载量下(Yb(OTf)3(0.4当量)或TfOH(0.5当量)),否则在相同的条件下,相同的反应通过正式的[4 + 2]环加成反应提供了1,6-二氢嘧啶17,收率良好。机理研究表明,两种环化反应都通过intermediate中间体,这是由于异氰基插入伯胺的NH键而引起的。随后依赖于催化剂负载的5- exo - dig或6- endo- dig环化反应分别有选择地提供了两个杂环。

  • Synthesis of <i>N</i>-Boc-Propargylic and Allylic Amines by Reaction of Organomagnesium Reagents with <i>N</i>-Boc-Aminals and Their Oxidation to <i>N</i>-Boc-Ketimines

    日期:2016.1.15
    N-Boc-protected propargylic and allylic amines were synthesized by the reaction between N-Boc-aminals and organomagnesium reagents through the in situ generated N-Boc-imine intermediates. The obtained N-Boc-propargylic amines could be readily converted into unprecedented N-Boc-ketimines by oxidation with manganese dioxide.

    AuI-catalyzed cyclization of N-Boc propargylamines into 4-alkylidene oxazolidin-2-ones is described. This modularapproach provides access to a variety of nonproteogenic 4-substituted oxazolidinones that are important in asymmetric synthesis and biological applications. The current flexible route is characterized by low catalyst loading, mild conditions, and operational simplicity.(© Wiley-VCH Verlag

    日期:2022.5
    reagents derived from terminal alkynes and trimethylaluminum underwent addition to various N-activated α-amido sulfones to produce the corresponding alkynylamines in moderate to excellent yields. The optimized protocol avoids the preparation and isolation of relatively unstable N-activated imines that are generated in situ from their corresponding, stable, N-activated α-amido sulfones. This methodology

    Abstract

    Synthesis of 2-fluoroalkylated oxazoles was developed by transition-metal-free intramolecular cyclization of N-propargylic amides, which are prepared from propargylic amines by employing a small excess of commercially available fluorocarboxylic acid anhydrides as fluoroalkyl­ sources, under basic conditions. Oxazoles bearing a trifluoro­methyl, pentafluoroethyl, or heptafluoropropyl group at the C2 position and functional groups on the C4 and/or C5 positions are obtained in moderate to high yields by controlling the reaction conditions.

    A general and selective method for the direct amidation of secondary benzyl alcohols with both sulfonamides and carbamates is described. This method has been applied to a variety of substrates and the reaction proceeded smoothly at room temperature in the presence of 5 mol % molybdenum(V) chloride to give the desired products in good yields.
