    作者:Yolanda Fernández Sainz、Steven A. Raw、Richard J. K. Taylor

    日期:2005.11.1
    Two separate strategies have been developed for the preparation of highly substituted pyridines from 1,2,4-triazines via the inverse-electron-demand Diels−Alder reaction: a microwave-promoted, solvent-free procedure and a tethered imine-enamine (TIE) approach. Both routes avoid the need for a discrete aromatization step and offer significant advantages over the classical methods, giving a wide variety
    已经开发了两种单独的策略,用于通过反电子需求的Diels-Alder反应从1,2,4-三嗪制备高度取代的吡啶:微波促进的无溶剂程序和束缚的亚胺-烯胺(TIE ) 方法。两种途径都避免了需要离散的芳构化步骤,并且与传统方法相比具有明显的优势,从而以高的,优化的产率提供了各种三,四和五取代的吡啶。

    a triazine ligand has a remarkable impact on the electronic and redox characteristics of the triruthenium cluster derivatives. Electrochemical, UV/Vis/NIR spectra, and DFT computational studies demonstrated that there is a distinct cluster–cluster interaction between the two triruthenium cluster moieties across an asymmetric bridging bis(tridentate) triazine in the dimeric triruthenium cluster complex

    The aza‐Diels–Alder cycloaddition of 1,2,4‐triazines with alkynes offers a rapid and convenient method for the synthesis of highly substituted pyridines, but often requires harsh conditions and long reaction times. The present study offers a solution to these limitations by use of a temporary tether established by a Lewis acid–base complexation of in situ generated alkynylboranes and triazines bearing
    1,2,4-三嗪与炔烃的氮杂狄尔斯-阿尔德环加成反应为合成高度取代的吡啶提供了一种快速便捷的方法,但通常需要苛刻的条件和较长的反应时间。本研究通过使用原位生成的带有路易斯碱性供体的炔基硼烷和三嗪的路易斯酸碱络合建立的临时系链,为这些限制提供了解决方案。环加成反应在 40 °C 下 20 分钟内发生,可直接获得各种吡啶,并具有完整且可预测的区域控制。碳-硼键可以通过交叉偶联进一步官能化,从而允许在环加成后引入更多官能团。

    The synthesis of perfluoroalkyl-substituted (hetero)arenes by benzannulation strategies is complementary to ring functionalization approaches as it obviates the need for pre-existing functionality and innate regiocontrol. We report a mild and regiospecific boron-directed benzannulation method as a vehicle for accessing a range of perfluoroalkyl-substituted (hetero)aromatic building blocks that can
    通过苯环化策略合成全氟烷基取代的(杂)芳烃与环功能化方法是互补的,因为它消除了对预先存在的功能和先天区域控制的需要。我们报告了一种温和且区域特异性的硼定向苯环化方法,可作为获得一系列全氟烷基取代(杂)芳族结构单元的载体,这些结构单元可以通过已建立的 C-B 键官能化过程轻松制备。
