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.

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.

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.

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.
