    摘要:
    将氟原子掺入有机基质中最简便,最可靠的方法之一是通过Halex氟化法。我们在这里描述了在温和条件下使用KF / DMSO系统对β-氯乙烯基醛进行的Halex氟化。进一步讨论了通过六个步骤的级联序列将氟取代的中间体转化为其二聚体化合物。

    Synthesis, characterization, and antimicrobial activity of novel substituted 2H-chromenyl acrylates
    摘要:
    The present study deals with conventional Witting olefination of 2H-chromene-3-carbaldehydes with stabilized ylide in the presence of dichloromethane to afford (2E)-ethyl-3-(4-chloro-2H-chromen-3-yl) acrylate derivatives. All the products were found to have E-geometry at C=C bond. The synthesized compounds were characterized by spectral data such as IR, H-1 NMR and MS. Compounds were screened for antimicrobial activity against strains of gram positive, gram negative bacterial and fungal strains. All compounds showed good antibacterial and antifungal activity.

    2-oxo-2H-chromenyl-5-oxo-2,5-dihydrofuran-3-carboxylates (5a-n) and 2H-chromenyl-5-oxo-2,5-dihydrofuran-3-carboxylates (8a-p). All the prepared compounds were screened for anti-inflammatory activity. In vitro anti-inflammatory activity data demonstrated that the compounds 5g, 5i, 5k-l and 8f are effective among the tested compounds against TNF-α (1.108 ± 0.002, 0.423 ± 0.022, 0.047 ± 0.001, 0.070 ± 0.002

  • Condensation of 4-chloro-2<i>H</i>-chromene-3-carbaldehydes and ethyl-3-aminocrotonates with <i>p</i>-TsOH: a facile approach for the synthesis of chromenyldihydropyridines

    The investigated reaction of 4-chloro-2H-chromene-3-carbaldehyde 1a with ethyl 3-oxobutanoate 2a in the presence of ammonium acetate provided two compounds, 2H-chromenyldihydropyridine dicarboxylate 3a and chromenopyridine carboxylate 4a. However, the reaction of 1a with ethyl-3-aminocrotonate 5a in the presence of p-TsOH provided selectively 2H-chromenyldihydropyridine dicarboxylate 3a with very good yield. The established method was applied for the preparation of series of 2H-chromenyldihydropyridine dicarboxylates 3a-q.
