  • A Metal-Free Domino Process for Regioselective Synthesis of 1,2,4-Trisubstituted Pyrroles: Application toward the Formal Synthesis of Ningalin B
    作者:Virendra Kumar、Annapurna Awasthi、Abhisek Metya、Tabrez Khan

    日期:2019.9.20
    acid/base-free domino process is developed for the regioselective synthesis of 1,2,4-trisubstituted pyrroles. The process involves 1,3-dipolar cycloaddition of unsymmetrical azomethine ylide resulting from the thermal C–C bond cleavage of unactivated aziridines with β-bromo-β-nitrostyrene, followed by a cascade of elimination and aromatization reaction sequence to preferentially furnish 1,2,4-trisubstituted
    开发了一种新的单锅,过渡属,无酸/无碱的多米诺骨牌工艺,用于区域选择性合成1,2,4-三取代的吡咯。该过程涉及不对称的偶氮甲内酯的1,3-偶极环加成反应,这是由于未活化的氮丙啶与β--β-硝基苯乙烯的热C–C键裂解所致,随后是一系列消除和芳构化反应序列,优先提供1,2 1,4-三取代的吡咯代替预期的1,2,3-三取代的吡咯,收率良好至极佳。此外,描述了该方法用于形式的宁格林B的合成。

    transmission along the aromatic system, thus enabling dynamic kinetic resolution via a traditional reversible deprotonation–protonation process. Enantioenriched 9-substituted 9H-fluorene frameworks were finally constructed through an asymmetric vinylogous Michael addition to nitroolefins, followed by a cascade cyclization and oxidative aromatization process, under the catalysis of a chiral bifunctional thiourea-tertiary
    3-取代的1-茚满酮的α,α-二基烯烃的苄基CH基团可以通过沿芳族体系传输而被显着活化,从而通过传统的可逆去质子化-质子化过程实现动态动力学拆分。最终通过在手性双官能硫脲-叔胺的催化下,将不对称乙烯基迈克尔加成至硝基烯烃,然后进行级联环化和氧化芳构化过程,来构建对映体富集的9-取代的9 H-骨架。
