  Research on antibacterial and antifungal agents. VIII. synthesis and antimicrobial activity of 1,4-diarylpyrroles

  摘要：

  The synthesis and the antimicrobial activity of 1,4-diarylpyrroles are reported. The obtained data in comparison with pyrrolnitrin show that many acid derivatives 4 exhibit a selective activity against some strains of Candida spp and poor activity against strains of Candida albicans. All ester derivatives 3 are inactive. The results obtained are discussed on the basis of structure-activity relationships.

• Triethanolammonium Acetate ([TEAH][OAc]) as a Recyclable Promoter and Medium for Green and Four-component Synthesis of Polyfunctionalized Pyrrole Derivatives
  作者：Behjat Pouramiri、Milad Daneshi、Fatemeh Seyedi、Najmeh Amirmahani

  DOI：10.2174/1570178617999200611150616

  日期：2021.3

  Multi-component synthesis of functionalized pyrrole derivatives was achieved via a fourcomponent condensation reaction of ethyl acetoacetate/ methyl acetoacetate, aromatic amines, nitromethane, and aromatic aldehydes using triethanolammonium acetate ([TEAH][OAc]) ionic liquid as a green solvent and catalyst. Easy access to highly substituted pyrroles, reusability of the catalyst, broad substrate scopes

  使用乙酸三乙醇铵（[TEAH] [OAc]）离子液体作为绿色溶剂和催化剂，通过乙酰乙酸乙酯/乙酰乙酸甲酯，芳香胺，硝基甲烷和芳香醛的四组分缩合反应，可以实现功能化吡咯衍生物的多组分合成。易于获得高度取代的吡咯，催化剂的可重复使用性，较宽的底物范围，无柱色谱法，反应时间短，产物收率高和无溶剂条件，使得该方案对环境友好且实用。
• Fe3O4@SiO2—CPTMS—Guanidine—SO3H-catalyzed One-Pot Multicomponent Synthesis of Polysubstituted Pyrrole Derivatives under Solvent-Free Conditions
  作者：H. Rostami、L. Shiri

  日期：2019.8

  A highly efficient procedure for the one-pot synthesis of polysubstituted pyrrole derivatives by the reaction between of aniline derivatives, beta-diketones or beta-ketoesters, and beta-nitrostyrene derivatives in the presence of Fe3O4@SiO2-CPTMS-guanidine-SO3H as a reusable magnetic nanocatalyst is reported. The magnetic nanocatalyst was prepared and fully characterized by FTIR spectroscopy, scanning electron microscopy, energy dispersive X-ray spectroscopy, X-ray diffraction analysis, thermogravimetric analysis, and vibrating sample magnetometry.
