Microwave spectra and structure of an isoxazole-water complex

The rotational spectrum of a hydrogen-bonded isoxazole-water complex has been measured between 6-18 GHz with a pulsed nozzle Fourier transform microwave spectrometer. In addition to isoxazole-H(2)O, the complexes with HDO and D(2)O as well as isoxazole-(15)N-H(2)O have been investigated in order to determine the structure of the complex. Rotational constants, quartic centrifugal distortion constants and quadrupole coupling constants, where applicable, have been fitted to the measured transition frequencies of the isotopomers. Structural data, which have been deduced from the planar moments of inertia and the quadrupole coupling constants of the isotopomers, have established conclusively that water binds to nitrogen in the ring plane of isoxazole. Ab initio calculations have revealed that complexes with a hydrogen-bond to nitrogen or to oxygen are both stable. The complex with water attached to nitrogen has been found to be more strongly bound than that with water attached to oxygen. Small splittings of the rotational transitions of the two complexes with H(2)O have been interpreted as being the result of an internal rotation of water with respect to isoxazole.

Harnessing the TEMPO-Catalyzed Aerobic Oxidation for Machetti-De Sarlo Reaction toward Sustainable Synthesis of Isoxazole Libraries

A practical synthesis of isoxazole/isoxazoline derivatives via Machetti-De Sarlo reaction under sustainable conditions has been accomplished. This protocol involves the use of readily available 2,2,6,6-tetramethylpiperidine-N-oxyl (TEMPO) to catalyze the cyclocondensation of primary nitroalkanes with alkynes/alkenes to afford a library of isoxazole/isoxazoline products. From an eco-benign perspective, notable advantages of this method are as follows: (i) water as the solvent, (ii) air as the oxidant, (iii) transition metal-free, (iv) no base required, (v) no toxic byproduct, (vi) no need of solvent extraction, (vii) diverse substrate scope, (viii) high chemical yields, (ix) excellent chemo- and regioselectivity, (x) short reaction time, (xi) gram-scale synthesis, (xii) extension to heterogeneous version, and (xiii) catalyst recyclability. For these reasons, the developed method is appropriate for safe laboratory use and can be expected to inspire the progress of TEMPO-based organocatalysis for the preparation of isoxazole/isoxazoline moieties in an environmentally benign fashion.

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.

Non-acidic 1,3,4-trisubstituted-pyrazole derivatives as lonazolac analogs with promising COX-2 selectivity, anti-inflammatory activity and gastric safety profile

Twelve new compounds of 1,3,4-trisubstituted-pyrazole derivatives possessing two cyclooxygenase-2 (COX-2) pharmacophoric moieties (SO2Me or/and SO2NH2) 11a-c, 12a-c, 13a-c and 14a-c were designed and synthesized to be evaluated for their COX inhibition, anti-inflammatory activity, ulcerogenic liability. All compounds were more selective for COX-2 isozyme and showed good in vivo anti-inflammatory activity. The bisaminosulphonyl derivatives (14a-c) were the most COX-2 selective compounds (S.I. = 9.87, 9.50 and 9.22 respectively) and showed good anti-inflammatory potency (ED50 = 15.06, 42.51 and 50.43 mumol/kg respectively) in comparison with celecoxib (COX-2 S.I. = 8.61, ED50 = 82.2 mumol/kg). Also, compounds 14a-c were less ulcerogenic (ulcer indexes = 2.72?3.72) than ibuprofen (ulcer index = 20.25) and comparable to celecoxib (ulcer index = 2.93). In addition, to explain the preferential (COX-2) inhibitory and selectivity, the designed compounds were subjected to molecular docking studies. It was found that compound 14c with the highest COX-2 activity and selectivity exhibited a binding pattern and interactions similar to that of celecoxib with formation of more hydrogen-bond features.
