Synthesis of novel steroidal oxazolo quinoxaline as antibacterial agents

Steroidal [oxazolo(4,5-b)quinoxaline-2-yl-hydrazone] derivative (7a-9a) (7b-9b) were prepared by the multi-step reactions of steroid. It is prepared via the reaction of steroidal semicarbazones with 2,3-dichloroquinoxaline at 80C in ethanol. The structures of the compounds were evident by IR, 1H NMR and mass spectrometry and their purities were confirmed by elemental analyses. The antibacterial activity of these compounds was evaluated by the disk diffusion assay against two Gram-positive and two Gram-negative bacteria and then the minimum inhibitory concentration (MIC) of compounds was determined. The results showed that compounds (7a, 7b, 8a, 8b) are better antibacterial agent as compared with the standard drug amoxicillin.

Method for preparing heterocyclic-carboxylic acids

The present invention relates to a method for preparing quinoxaline-5- and 6-carboxylic acids. The method comprises contacting an aqueous suspension of a 5- or 6-hydroxymethyl quinoxaline with oxygen in the presence of a transition metal catalyst, to form the respective quinoxaline-5- or 6-carboxylic acid. The method for oxidizing benzylic methyl groups may also be employed to prepare a wide variety of heterocyclic carboxylic acid compounds.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 6344-72-5 is helpful to your research. Application of 6344-72-5

Non-symmetrical three and two-core ring mesogens based on quinoxaline and benzimidazole derivatives: Supramolecular layers through amphoteric donating/accepting H-bonds

Self-assembly-based molecular structures have proven to be highly relevant to the development of soft materials. This work reports the synthesis, thermal behavior and computational analysis of two novel heterocyclic compounds with a non-symmetrical shape bearing a single long alkyl (C12) chain. The compounds 2-(4-dodecyloxy-phenyl)-1H-benzoimidazole, 1, with three-ring core mesogen with a more linear shape, and 1-dodecyl-1,4-dihydro-quinoxaline-2,3-dione, 2, with a condensed two-ring core with a more compact discotic shape, were obtained in good yields and investigated by polarized optical microscopy (POM) and differential scanning calorimetry (DSC) analysis. Benzimidazole derivative 1 was found to present liquid crystalline property, with a mesophase range from 85 to 177 C, as verified by POM and DSC, with a smectogenic polymorphism assigned as a SmB and a more organized unidentified SmX phase. On the other hand, although quinoxaline 2 did not show liquid crystal behavior, POM analysis indicated an interesting spherulitic packing pattern, typical of a columnar arrangement of the molecules by possible H-bond interactions. Computational results indicated that combining intermolecular hydrogen bonds and hydrophobic interactions lead to a non-planar lamellar model for benzimidazole 1, consistent with the smectic packing found in the liquid crystalline phase and a twist-type packing for compound 2, which is consistent with a spherulitic model.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 15804-19-0 is helpful to your research. Related Products of 15804-19-0

Direct and Regioselective C-H Oxidative Difluoromethylation of Heteroarenes

The difluoromethyl group (CF2H) is of great interest in the area of medicinal chemistry. However, the investigation of molecular scaffolds containing this group has been hampered by the limitation of synthetic methods for the introduction of CF2H into heteroarenes. Herein we disclose a new strategy for the direct introduction of a difluoromethyl group into heteroarenes via the copper-mediated C-H oxidative difluoromethylation of heteroarenes with TMSCF2H. This mild and regioselective method enables the convenient synthesis of a range of difluoromethylated heteroarenes in high yields. The usage of 9,10-phenanthrenequinone (PQ) as an oxidant is critical to the success of this new difluoromethylation reaction.
