PREPARATION OF CROWN ETHERS WITH ISOXAZOLYL-LARIATS – HOMOLOGATION OF ISOXAZOLE ALDEHYDES, AND A CRITICAL COMPARISON OF LARIAT FUNCTIONAL MOIETIES FOR LANTHANIDE EXTRACTION

A critical comparison of several lariat ether functional moieties is presented. The synthesis of two isoxazolyl-lariat ethers is described. The lariat ether (2, n = 1) undergoes B-fragmentation on electron transfer reductive ring-opening with samarium diiodide. The isoxazole moiety was then homologated to overcome this problem, and isoxazole lariat ether (2, n = 3) was obtained. The isoxazole (2, n = 3) and beta-diketone (3, n = 3) crowns were evaluated in lanthanide shift studies and liquid-liquid extraction studies. Finally, lateral metalation and electrophilic quenching with carbon dioxide produced the carboxylic acid (12) which proved to be an efficient ligand for the liquid-liquid extraction of lanthanides.

Synthetic isoxazole as antiplatelet agent

Nine synthetic isoxazoles were evaluated as antiplatelet agents and studied the possible mechanism of more active compound. The initial screening was evaluating all compounds against platelet aggregation assays. The most active compound was isoxazole 8 showing an inhibition of platelet aggregation around 70%. In subsequent experiments, ADP and collagen were used as agonists to explore the possible inhibitory mechanisms of isoxazole 8 in platelet aggregation and secretion. We reported the effect of isoxazole 8 for reducing the expression of inflammatory markers, such as soluble CD40 ligand (sCD4OL) and soluble P-selectin (sP-selectin), on activated platelets. Of this form, an inhibition of sCD4OL and sP-selectin can prevent the onset of an atherosclerotic lesion.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 1076-97-7, you can contact me at any time and look forward to more communication. Category: Isoxazoles.

Theoretical study of thermal decomposition mechanisms of isoxazole

Density functional theory and ab initio calculations were carried out to investigate two probable unimolecular decomposition channels of isoxazole. The calculated structural parameters, dipole moment, and vibrational frequencies of isoxazole are in good agreement with available experimental data. Relative energies of transition states and equilibrium structures evaluated at MP4 and QCISD(T) levels of theory at B3LYP/6-31G** structures indicate that CO and CH3CN, major products of isoxazole thermal decomposition in the temperature range 850-1100 K, are unlikely produced via the mechanism proposed in the experimental and previous theoretical studies. Instead, the mechanism proposed in the current study, isoxazole –> NCCH2CHO –> CH3CN + CO, is more likely the main unimolecular decomposition channel. The mechanism proposed in the experimental study was shown to have a higher activation barrier and is likely responsible for the formation of HCN and H2CCO, minor products of isoxazole decomposition.

3-(Arylthiomethyl)isoxazole-4,5-dicarboxamides: Chemoselective Nucleophilic Chemistry and Insecticidal Activity

A collection of 91 3-(arylthiomethyl)isoxazole-4,5-dicarboxamides was prepared starting from dimethyl 3-(chloromethyl)isoxazole-4,5-dicarboxylate. The thioether moieties in these compounds were subsequently oxidized to give the corresponding 3-(arylsulfonylmethyl)isoxazole-4,5-dicarboxamides. By carefully controlling stoichiometry and reaction conditions, the C4 and C5 carbomethoxy groups could be differentially derivatized to carboxamides. A total of 182 trisubstituted isoxazoles are reported and deposited in the National Institutes of Health Molecular Repository; an 80 compound subset was evaluated for insecticidal activity.

The synthetic and therapeutic expedition of isoxazole and its analogs

Isoxazole, constituting an important family of five-membered heterocycles with one oxygen atom and one nitrogen atom at adjacent positions is of immense importance because of its wide spectrum of biological activities and therapeutic potential. It is, therefore, of prime importance that the development of new synthetic strategies and designing of new isoxazole derivatives should be based on the most recent knowledge emerging from the latest research. This review is an endeavor to highlight the progress in the chemistry and biological activity of isoxazole derivatives which could provide a low-height flying bird’s eye view of isoxazole derivatives to the medicinal chemists for the development of clinically viable drugs using this information.
