  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.

  Cryptosporidium inosine 5′-monophosphate dehydrogenase (CpIMPDH) has emerged as a therapeutic target for treating Cryptosporidium parasites because it catalyzes a critical step in guanine nucleotide biosynthesis. A 4-oxo-[1]benzopyrano[4,3-c]pyrazole derivative was identified as a moderately potent (IC50 = 1.5 μM) inhibitor of CpIMPDH. We report a SAR study for this compound series resulting in 8k

  enolate α-alkenylation of ketones is presented; the formation of aromatic compounds is a new direction for this catalytic C–C bond forming reaction. In the key step, a protected β-haloalkenylaldehyde participates in α-alkenylation with a ketone to afford a 1,5-dicarbonyl surrogate, which then undergoes cyclization/double elimination to the corresponding pyridine product, all in one pot. The β-haloalkenylaldehyde

  提出了一种基于钯催化酮的​​烯醇化α-烯基化反应的高取代吡啶合成的新方法。芳族化合物的形成是该催化性CC键形成反应的新方向。在关键步骤中，受保护的β-卤代烯醛与酮一起参与α-烯基化反应，以提供1,5-二羰基替代物，然后对其进行环化/双消除反应，形成相应的吡啶产物，全部集中在一个罐中。β-卤代烯基醛原料可以通过Vilsmeier卤代甲酰基化从相应的亚甲基酮获得。使用这种简洁的方法，可以从市售化合物的三个步骤中合成出各种高度取代的吡啶。
