Probing the adsorption behavior of oxazole and isoxazole heterocyclic compounds onto B12N12 nanocluster surface in gas and aqueous mediums through DFT calculations

The adsorption of oxazole and isoxazole molecules over the pristine B12N12 nanocluster is investigated in terms of its geometric, the adsorption energies and the electronic properties using density functional theory calculations. The results indicate that the pristine cluster effectively chemisorbs with the oxazole and isoxazole molecules through their nitrogen atoms; whereas the interaction through the oxygen atoms is not considerable. The HOMO-LUMO gap of the cluster decrease by the adsorption of heterocycle rings. The role of solvent in improving the adsorption properties over the B12N12 surface is also considered. The obtained adsorption energies in aqueous medium are more negative than gas phase implied to the stability of the B12N12/ heterocycles complexes in the aqueous medium. Indeed, the interactions of some oxazole and isoxazole derivatives with this cluster are also investigated. The current study provides the knowledge about the performance of the B12N12 cluster in adsorbing oxazole and isoxazole moleculest.

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 1779-51-7 is helpful to your research. Product Details of 1779-51-7.

Green multicomponent synthesis, antimicrobial and antioxidant evaluation of novel 5-amino-isoxazole-4-carbonitriles

Background: Design and synthesis of new inhibitor agents to deal with pathogenic microorganisms is expanding. In this project, an efficient, environmentally friendly, economical, rapid and mild procedure was developed for the synthesis of novel functionalized isoxazole derivatives as antimicrobial potentials. Methods: Multicomponent reaction between malononitrile (1), hydroxylamine hydrochloride (2) and different aryl or heteroaryl aldehydes 3a-i afforded novel 5-amino-isoxazole-4-carbonitriles 4a-i in good product yields and short reaction times. Deep eutectic solvent K2CO3/glycerol was used as catalytic reaction media. Structure of all molecules were characterized by different analytical tools. In vitro inhibitory activity of all derivatives was evaluated against a variety of pathogenic bacteria including both Gram-negative and Gram-positive strains as well as some fungi. In addition, their free radical scavenging activities were assessed against DPPH. Results: Broad-spectrum antimicrobial activities were observed with isoxazoles 4a, b, d. In addition, antioxidant activity of isoxazole 4i was proven on DPPH. Conclusions: In this project, compounds 4a, b, d could efficiently inhibit the growth of various bacterial and fungal pathogens. Antioxidant properties of derivative 4i were also significant. These biologically active compounds are suitable candidates to synthesize new prodrugs and drugs due to the presence of different functional groups on their rings.

Selective reduction of 4-substituted 3-aryl-5-trifluoromethylisoxazole by NaBH4

A series of 4-substituted 3-aryl-5-trifluoromethyl-4,5-dihydroisoxazole derivatives was synthesized by selective reduction of the corresponding 3-aryl-5-trifluoromethyl-4-isoxazole with NaBH4 under various reaction conditions. It was found that the reduction selectivity of endocyclic carbon-carbon double bond of the isoxazole ring was strongly dependent on the electronic effects of substituents at C-4 of trifluoromethylated isoxazoles. Meanwhile, the solvent effects also had a great influence on the reduction selectivity of endocyclic carbon carbon double bond of the 4-iminoyl substituted isoxazole ring.

The preparation of an isoxazole derivative of 4-hydroxycoumarin

A method for preparation of an isoxazole derivative of 4-hydroxycoumarin, 3-phenyl-5-(4-hydroxy-3-coumarinyl)-isoxazole has been described. The reaction sequence includes addition of bromine to 3-cinnamoyl-4-hydroxycoumarin, and the subsequent treatment of the obtained dibromo derivative with 2 equivalents of sodium azide. Due to steric reasons, the azido group is introduced in the beta-position with respect to the side chain carbonyl group, so that an isoxazole ring can be formed. The total yield of the reaction was 58%.

SYNTHESIS OF UNSYMMETRICALLY SUBSTITUTED ISOXAZOLES AS INTERMEDIATES FOR BENT-CORE MESOGENS

3,5-Disubstituted isoxazoles have been designed and synthesized to be used as central units for bent-core mesogens. The substituents at position 3 of the isoxazole ring are either hydroxymethyl or carboxyl, while alkenyl-terminated substituents have been inserted at position 5. A multi-step reaction sequence comprising the O-alkylation of 4-hydroxyacetophenone with the suitable alkenyl halide, the Claisen-type condensation with diethyl oxalate and the cyclization to isoxazole led to the isoxazole esters as key intermediates, which were subsequently reduced and hydrolyzed to the corresponding isoxazol-3-ylmethanols and isoxazole-3-carboxilic acids, respectively.
