Synthesis of 4-Alkenyl Benzoxazoles via Pd-catalyzed ortho C-H Functionalization of 2-Amidophenols

A one-pot direct transformation to remotely C-H alkene functionalized 2-aryl benzoxazoles from the reaction of amidophenol and electronically deficient olefin was reported. Control experiments confirm that the Pd-catalyzed regioselective C-H activation/alkenylation occurs at the first step by leading to ortho-alkenylated amidophenol; which subsequently underwent tandem intramolecular annulation to afford C4-alkenylated 2-arylbenzoxazole derivatives.

A reaction mechanism is the microscopic path by which reactants are transformed into products. Each step is an elementary reaction. In my other articles, you can also check out more blogs about 92-86-4. Computed Properties of C12H8Br2.

Prediction of circulating human metabolites of pemafibrate, a novel antidyslipidemic drug, using chimeric mice with humanized liver

Pharmacokinetics and metabolism of recently launched antidyslipidemic drug pemafibrate ((2R)-2-[3-({1,3-benzoxazol-2-yl[3-(4-methoxyphenoxy)propyl]amino}methyl)phenoxy]butanoic acid) was investigated in chimeric mice with humanized liver in the present study. The plasma unbound fractions of [C-14]pemafibrate in mice (0.0046-0.0048) were higher than those in monkeys and humans (0.0015-0.0022). In chimeric mice with humanized liver intravenously treated with pemafibrate at 1.0 mg/kg body weight, the pharmacokinetic parameters (CLtotal, V-ss and AUC(0-inf)) of unbound pemafibrate in chimeric mice with humanized liver were more similar to those reported in monkeys and humans than those in control mice. High concentrations of N-dealkylated form (M4) and benzoxazole 6-hydroxylated form (M6) of pemafibrate in plasma were observed as the main circulating metabolites in chimeric mice with humanized liver treated with pemafibrate. Moreover, the concentrations of other specified metabolites of pemafibrate were much higher in chimeric mice with humanized liver than in control mice. These results suggest that there are species differences in the pharmacokinetics of pemafibrate in vivo between mice tested and humans reported. Moreover, chimeric mice with humanized liver seem to be a beneficial animal model for further studies to predict the circulating human metabolites of pemafibrate and their pharmacokinetics.

Synthesis of thioethers, arenes and arylated benzoxazoles by transformation of the C(aryl)-C bond of aryl alcohols

Transformation of aryl alcohols into high-value functionalized aromatic compounds by selective cleavage and functionalization of the C(aryl)-C(OH) bond is of crucial importance, but very challenging by far. Herein, for the first time, we report a novel and versatile strategy for activation and functionalization of C(aryl)-C(OH) bonds by the cooperation of oxygenation and decarboxylative functionalization. A diverse range of aryl alcohol substrates were employed as arylation reagentsviathe cleavage of C(aryl)-C(OH) bonds and effectively converted into corresponding thioether, arene, and arylated benzoxazole products in excellent yields, in a Cu based catalytic system using O(2)as the oxidant. This study offers a new way for aryl alcohol conversion and potentially offers a new opportunity to produce high-value functionalized aromatics from renewable feedstocks such as lignin which features abundant C(aryl)-C(OH) bonds in its linkages.

Investigation of thermal and fluorescent properties of benzoxazole-linked triphenylamine-based co-polyimides

A series of novel fluorescent co-polyimides are obtained by combining N (1)-(4-aminophenyl)-N (1)-(4-(benzo[d]oxazol-2-yl) phenyl) benzene-1,4-diamine and 4,4 ‘-oxydianiline with four aromatic anhydride, 3,3 ‘,4,4 ‘-benzophenonetetracarboxylic dianhydride, pyromellitic dianhydride, 4,4 ‘-oxydiphthalic anhydride, and 4,4 ‘-(hexafluoroisopropylidene)diphthalic anhydride following conventional polycondensation method. The resultant co-polyimides are characterized by elemental, Fourier transform infrared spectral analysis and gel permeation chromatography. All newly prepared polyimides (PIs) exhibit shallow highest occupied molecular orbital energy levels in the range of -4.47 to -4.98 eV and have reasonable optical bandgaps. The photoluminescence spectral analysis shows blue to green emission in solution form. Thermal and solubility properties reveal that the PIs with pendant 4-(benzo[d]oxazol-2-yl group linked to triphenylamine unit in polymer backbone impart not only good thermal stability but also appreciable solubility making these new co-polyimides versatile for multipurpose usage.

Out of the fourteen newly synthesized compounds; 3b, 3d, 3e, 3h, 31 and 3m were found to be most potent COX-2 inhibitors in in vitro enzymatic assay with IC 50 in the range of 0.14-0.69 mu M. In vivo anti-inflammatory activity of these six compounds (3b, 3d, 3e, 3h, 31 and 3m) was assessed by carrageenan induced rat paw edema method. The compound 3b (79.54%), 31 (75.00%), 3m (72.72%) and 3d (68.18%) exhibited significant anti-inflammatory activity than standard drug ibuprofen (65.90%).
