  Design, synthesis and anti-mycobacterial activity of 1,2,3,5-tetrasubstituted pyrrolyl-N-acetic acid derivatives

  摘要：

  A novel synthesis of highly substituted pyrrole-N-acetic derivatives is described through the coupling of 1,4-diketones with amino acids following Paal-Knorr's approach. These pyrrole-N-acetic acid derivatives are found to exhibit potent anti-mycobacterial activity against Mycobacterium smegmatis and Mycobacterium tuberculosis strain H37Rv. In particular, 5n, 5q &5r are found to display excellent anti-mycobacterial activity against M. tuberculosis strain H37Rv with MIC values in the range of 2.97 μM. Conversely, these compounds showed low cytotoxicity (selectivity index: >16.83) against HEK-293T cell line.

• Dual NHC/photoredox catalytic synthesis of 1,4-diketones using an MR-TADF photocatalyst (DiKTa)

  The use of the recently reported organic multi-resonant thermally activated delayed fluorescence (MR-TADF) photocatalyst DiKTa allows for the modular synthesis of 1,4-diketones under mild and metal-free conditions. The reaction proceeds via a three-component relay process in the presence of an N-heterocyclic carbene (NHC) organocatalyst.

  Efficient and modular synthesis of structurally diverse 1,4-diketones from readily available building blocks represents an essential but challenging task in organic chemistry. Herein, we report a multi-component, regioselective bis-acylation of olefins by merging NHC organocatalysis and photoredox catalysis. With this protocol, a broad range of 1,4-diketones could be rapidly assembled using bench-stable

  从容易获得的结构单元中高效、模块化地合成结构多样的 1,4-二酮是有机化学中一项重要但具有挑战性的任务。在此，我们报道了通过结合 NHC 有机催化和光氧化还原催化实现烯烃的多组分、区域选择性双酰化。通过该方案，可以使用实验室稳定的原料材料快速组装多种 1,4-二酮。通过敏感性筛选进一步评估了该方法的稳健性，并观察到良好的重现性。此外，二酮产物可以很容易地转化为官能化杂环，例如多取代的呋喃、吡咯和哒嗪。机理研究揭示了 NHC 和光氧化还原双催化自由基反应机理。
